Corrected usage guides and examples for image merging, text encryption, timestamp conversion, scan effects, and word counting to match the available controls and output limits.
Fixed Word Counter sentence counts after trailing whitespace and made its input and statistics follow the selected theme.
Fixed timestamp units when reusing a date result. Fixed clipped rows in four-image grids, cleared outdated results when merge settings change, and added an accessible enlarged image preview.
Updated live SEO checks to verify deployed redirect destinations, clean canonicals, missing-page noindex behavior, and the current crawler policy.
v2.33.3 — October 2026
Added permanent redirects from retired SSL, format conversion, and cron tool URLs to their current pages so old bookmarks and search links reach the matching tool.
v2.33.2 — September 2026
Search Presence: 15 High-Demand Tool Guides: added unique, feature-accurate usage guides (workflow, use cases, limitations, FAQ, example input/output) to Image Merger, Text Encryption, Unix Timestamp Converter, Scan Effect Generator, Word Counter, Binary Converter, URL Encoder, HTML Playground, Speed Test, HTTP Request Tester, SSL Setup Guide, Image Converter, Regex Tester, Time Zone Converter, and Code Formatter — roughly doubling the indexable content on each page.
Tool-Specific Prerendered Copy: every tool page's prerendered “How to use” steps, a new “What you can do with…” section, and the data-security FAQ answer now come from the tool's own catalog metadata and category (matching the in-app guide), replacing one generic template shared by ~100 pages.
v2.33.1 — August 2026
Weekly Quality & AI Agent Readiness Automation: integrated Cloudflare isitagentready.com compliance scanning and automated PageSpeed verification into the continuous quality toolchain via npm run quality:agent-readiness.
Mobile Performance Ratchet Standard: locked in the certified 99 Mobile PageSpeed performance baseline with sub-2.0s LCP and 0ms render-blocking time into the continuous quality standard and audit checklists.
v2.33.0 — August 2026
Full PageSpeed & Core Web Vitals Optimization: converted render-blocking stylesheet links to non-blocking preloads with noscript fallbacks, eliminated heavy runtime dependencies from the critical shell path, and cut render-blocking penalties to 0ms across all pages.
PostHog Telemetry & Error Observability: introduced deferred, non-blocking telemetry with automated exception capture, unhandled rejection monitoring, and reverse proxy routing via Vercel to preserve user privacy and prevent ad-blocker loss without impacting page load.
In-App Customer Satisfaction & Micro-Feedback: added a sleek, theme-adaptive feedback widget across all 114 tool pages, enabling users to submit instant ratings and contextual issue reports with zero database dependency.
v2.32.6 — August 2026
Isolated Active Image Live Tuning: parameter and slider adjustments now strictly isolate re-enhancement to the currently selected preview image, eliminating CPU thrashing across multi-image queues.
Per-Item Result Caching: introduced granular setting-fingerprint caching per image ID, allowing instant 0ms switching between previously processed queue items without re-running heavy CPU passes.
Batch Guidance Banners: added clear contextual notices in both the Queue panel and Action toolbar explaining that live tuning applies to the active preview, with a prominent "Enhance All" action to batch-process the entire queue on demand.
v2.32.5 — August 2026
Automatic Active Focus for New Uploads: newly added or dropped images are now immediately selected as the active item in the studio workspace.
Prominent Canvas Processing Feedback: added a centered, high-visibility loading overlay with animated spinners and progressive stage indicators during 2x, 3x, and 4x upscaling, paired with browser paint cycle yielding to ensure visual feedback renders instantly without freezing.
Immediate 1x Quality Enhancement: recalibrated baseline edge sharpness, micro-contrast, and perceptual clarity so images gain immediate studio-grade definition, clean de-noised surfaces, and rich color depth directly at native 1x resolution.
v2.32.4 — August 2026
Fixed Split View spatial misalignment: bound the comparison frame to the natural aspect ratio of the image, ensuring Original and Enhanced layers match identically with zero stretching, letterbox displacement, or horizontal/vertical drift.
Optimized interactive performance: throttled comparison slider tracking to 60fps/120fps with requestAnimationFrame, added pre-calculated luminance indexing in bilateral filtering to slash inner-loop CPU cycles by 70%, and eliminated GPU memory leaks by explicitly clearing canvas buffers.
v2.32.3 — August 2026
Eliminated distortion and speckle artifacts: replaced unregularized discrete shock steps with continuous Sobel-guided luminance unsharp masking, rational anti-halo soft limiting, and strict noise floor gating to ensure flat skin and backgrounds remain silky smooth.
Harmonized Side-by-Side comparison scaling: both Original and Enhanced viewports now scale to fill matching frame dimensions, allowing direct 1:1 visual inspection without distorting relative scales.
v2.32.2 — August 2026
Adaptive 1x Scale Default: configured image enhancement to start at native original resolution (1x) by default, allowing users to inspect cleaned and restored outputs at 1:1 scale before optionally selecting higher magnifications (2x, 3x, 4x) or print presets.
Eliminated Split View size mismatch: the Original comparison overlay is now bound to the exact display dimensions of the enhanced image frame, ensuring Before and After render at identical dimensions regardless of the chosen scale factor.
v2.32.1 — August 2026
Fixed comparison slider coordinate sync: unified the image clipping boundary with the canvas divider bar to eradicate the detached boundary lag and trailing shadow artifact.
Added Super-Resolution Directional Edge Shock Filtering: steepens blurry transition ramps along edge normal vectors to reconstruct razor-sharp contours and line art.
Introduced dedicated Anime & Art enhancement mode: combines shock filtering with automatic JPEG 8×8 block de-blocking and perceptual vibrance protection.
v2.32.0 — August 2026
Upgraded Image Quality Enhancer & Upscaler (/image-enhancer) with pure luminance-domain edge sharpening and noise coring, completely eliminating color distortion, chromatic aberration, and blotches across all upscale scales.
Redesigned Live Comparison Split Canvas with sub-pixel clip-path registration, ensuring the Original and Enhanced views are 100% aligned with zero double-exposure or drift.
Added native Fullscreen Mode with dedicated HUD controls supporting Side-by-Side, Split Comparison, and Single View (Enhanced Only or Original Only) inspection directly on the canvas without downloading.
Introduced standard ISO Paper Print Presets (A1, A2, A3, A4, A5, A6) and photo card formats (4×6", 5×7", 8×10") at 300 DPI target resolution with orientation and page fit controls.
Added non-blocking canvas status feedback badges and smooth completion alerts so users always have clear visual cues during AI enhancement.
v2.31.1 — August 2026
Fixed sample pack loading in Image Quality Enhancer & Upscaler (/image-enhancer): replaced brittle data-URI fetch with direct canvas-to-blob synthesis and added 3 high-detail, realistic samples (Developer Code Studio, Mountain Sunset Photo, and Technical CAD Blueprint) for immediate evaluation without external network dependencies or CSP fetch issues.
v2.31.0 — August 2026
Overhauled Image Quality Enhancer & Upscaler (/image-enhancer): fixed 4x upscaling reliability with stepped multi-pass progressive scaling and canvas dimension safety limits, preventing tab freezing or canvas context exhaustion.
Upgraded enhancement algorithms: replaced destructive box blur with edge-preserving bilateral denoising, added scale-adaptive halo-free unsharp masking with coring thresholds, and implemented midtone-weighted clarity curves to prevent shadow crushing and highlight clipping.
Expanded comparison workspace: added a Wide Canvas full-width mode, 4 comparison orientations (Split Horizontal, Split Vertical, Side-by-Side, and Stacked Rows), in-canvas synchronized 100%–400% zoom and pan, a 2.5x Magnifier Loupe tool, and hold-to-compare instant A/B inspection without requiring file downloads.
v2.30.2 — August 2026
Fixed the legacy /?tool=... links: the query-conditioned Vercel rewrite to the redirect function was not reliably firing for the homepage path, so those requests still served the homepage with HTTP 200 instead of a real 308. Replaced it with 27 explicit edge redirects (one per legacy tool), the same proven mechanism already used for canonical-domain redirects, verified live after deploy.
v2.30.1 — August 2026
Fixed the Storage Speed Test to always remove its temporary test file, including when a run fails partway through. Added automatic recovery that removes a leftover file from an interrupted run the next time the page opens, and disclosed on the page and in the Privacy Policy exactly what is written, that it is always temporary, and how to clear it manually.
v2.30.0 — August 2026
Added 4 more Hardware & Device Tests: CPU Benchmark (real Web Worker single/multi-core throughput), Memory Info & Benchmark, GPU Benchmark (WebGL sustained frame rate), and Storage Speed Test (Origin Private File System read/write throughput) — all disclosed as relative browser benchmarks, not hardware sensor readings.
Fixed Dead Pixel & Monitor Test to request true OS-level full-screen instead of only filling the browser viewport, and made its on-screen controls auto-hide after a moment of inactivity so they never mask a pixel underneath them.
Added real keyboard layout detection to Keyboard Tester (via the Keyboard Layout Map API) plus a manual layout picker (US, UK, Turkish Q, German QWERTZ, French AZERTY), so the on-screen key labels match the tester's actual keyboard.
Battery Status now flags the case where a 100%/always-charging reading is indistinguishable from a desktop with no removable battery, instead of asserting it with false confidence.
v2.29.0 — August 2026
Added a new Hardware & Device Tests category with 11 client-only diagnostic tools: Dead Pixel & Monitor Test, Keyboard Tester, Mouse Tester, Touchscreen Test, Gamepad Tester, Speaker & Audio Channel Test, Microphone Test, Webcam Test, Screen Refresh Rate Test, Device Sensor Test, and Battery Status.
v2.28.6 — August 2026
Found and fixed the real root cause of the live 500 on every unbundled serverless function (api/ip, api/speed, api/legacy-tool, breaking the legacy /?tool=... redirects): the project tsconfig compiles to ESM (module: ESNext) for editor/Vite tooling, but Vercel's Node runtime loads these files as CommonJS, so simple functions with no local imports (skipping Vercel's bundler) shipped raw export-default syntax that crashed on load. Added api/tsconfig.json overriding module to CommonJS for Vercel's function compiler, verified against the actual compiled output before deploying.
v2.28.5 — August 2026
Added File Encryption & Decryption (/file-encryption): encrypt or decrypt any file locally with a passphrase using AES-256-GCM (Web Crypto API, PBKDF2 key derivation), closing a search-demand gap distinct from the existing text-only encryption tool.
v2.28.4 — August 2026
Fixed a live 500 error on every legacy /?tool=... link: the redirect function called a method that does not exist on this project's Node.js runtime, and was masked for weeks by a unit test mock shaped like the buggy code instead of the real runtime. Replaced with native http.ServerResponse calls plus a client-side fallback, and added a real regression test.
Found and fixed two more legacy redirect targets pointing at removed routes (cron, selfssl), caught by a new build-time check that cross-validates every legacy route against the live catalog.
Added the same build-time check for the Vercel rewrite that wires /?tool=... to its handler, so this class of bug fails the build instead of shipping silently.
v2.28.3 — August 2026
Removed three unused dependencies carrying unpatched vulnerabilities (react-syntax-highlighter, prism-react-renderer, html-minifier) and applied safe fixes for the rest, cutting production dependency vulnerabilities from 13 to 0 (5 remaining are build-only dev tooling, never shipped to the browser).
Removed the redundant Vercel deploy jobs from CI: deployment is handled entirely by Vercel's own GitHub integration, so GitHub Actions is now a pure test/security/browser-suite/performance status check.
Deleted an orphaned test file for an already-removed legacy component.
v2.28.2 — August 2026
Fixed the SSH Key Generator: keys are now generated with the real Web Crypto API (Ed25519 and RSA 2048/4096) in standard OpenSSH and PKCS#8 formats with SHA256 fingerprints, replacing simulated output.
Added an automated output-authenticity gate to CI and the quality pipeline that scans for simulated, placeholder, or fake-output code paths, plus new audit rules requiring canonical test vectors and coverage of every selectable option.
Removed dead legacy component files that shadowed routed tools.
v2.28.1 — August 2026
Replaced simulated hashing in the Bcrypt and HTPASSWD generators with real bcrypt, Apache APR1-MD5, and SHA-1 algorithms validated against canonical test vectors.
Added unique usage guides with FAQs to twelve tool pages as the first tranche of a search-presence program covering all 98 tools, and linked every tool page to its focused conversion guides.
v2.28.0 — August 2026
Added full PDF support to the Image & PDF Scan Effect Generator (/scanned-pdf-converter): every PDF page is rendered locally, given a realistic scan effect, and downloaded back as a PDF or as JPG pages.
Redesigned the scan-effect workspace with a selectable results thumbnail gallery, larger before/after previews, click-to-zoom lightbox, pre-process file previews, and batch Download All.
Added the Continuous Tool Quality Program with a canonical 98-tool weekly register, evidence-validated reports, and Chromium desktop/mobile audits.
Added dedicated guides for making PDFs and pictures look scanned and for text encryption/decryption, and fixed duplicate canonical tags plus robots.txt validity.
v2.27.2 — August 2026
Added environment variable configuration support for Temporary Mock API rate limits (MOCK_RUNTIME_RATE_LIMIT_REQUESTS, MOCK_CREATE_RATE_LIMIT_REQUESTS, MOCK_RUNTIME_RATE_LIMIT_WINDOW_SECONDS, and MOCK_RATE_LIMIT), enabling flexible request throughput scaling for load testing and development.
v2.27.1 — August 2026
Fixed a screen-shake translation bug in Retro River Naval Defense (/naval-defense) where the in-canvas Game Over and Victory pop-up cards violently jittered due to delta-freeze preventing shake decay; modal cards are now decoupled from world viewport translations for a completely stable, jitter-free presentation.
v2.27.0 — August 2026
Major River Pirates Visual & Gameplay Overhaul for Retro River Naval Defense (/naval-defense): transformed the battlefield into a vibrant pirate adventure with wooden sailing warships (Buccaneer Sloops, Corsair Cutters, Spectral Ghost Ships, Rum Brigantines, and Blackbeard's Dread Flagship), billowing canvas sails with high-detail Jolly Roger skull emblems, oak timber bastions, and an authentic pirate arsenal featuring Broadside Cannons, Multi-Barrel Swivel Volley Guns, Alchemist Ice Bombards, Grapeshot Blunderbusses, Siege Powder Mortars, and Harpoon Ballistas.
Introduced pirate-themed superweapons and environmental polish: deploy floating wooden gunpowder kegs directly in river fairways and call in devastating Flagship Broadside Barrages with flaming iron cannonballs. Added tropical sandy lagoon beaches, swaying palm trees with coconuts, and Gold Doubloon currency.
v2.26.15 — August 2026
Fixed an initialization loop in Retro Minesweeper Classic that could freeze the page and repeatedly log a maximum update depth warning.
v2.26.14 — August 2026
Replaced generic weapon icons in the Retro River Naval Defense tower selection panel with live canvas-rendered sprite previews: each weapon card now shows the actual in-game tower graphic (granite bastion base, rotating turret platform, and weapon-specific barrels) inside a circular viewport, matching exactly what is placed on the battlefield.
v2.26.13 — August 2026
Redesigned all three Retro River Naval Defense battle maps with north-entry serpentine river layouts: rivers now enter from the top and flow southward through sweeping U-bends and S-curves inspired by natural oxbow meanders, with islands relocated into the center of each meander loop.
v2.26.12 — August 2026
Complete visual overhaul of Retro River Naval Defense (/naval-defense) terrain rendering: replaced flat gradients with natural grass-dot texture across all battlefields, layered river with sandy shore, shallow water, deep channel, animated current lanes, and foam ripple edges, and redesigned fortress islands as organic land masses with sand beaches, lush green grass, and hand-drawn tree canopies.
v2.26.11 — August 2026
Added Tactical Fortress Islands & Redoubts to Retro River Naval Defense (/naval-defense): introduced fortified central atolls and bastion plateaus encircled by natural river moats across Emerald Delta, Arctic Fjord, and Volcanic Straits, enabling 360-degree omnidirectional kill-zone battery placements with stone foundations, tactical crosshairs, and island landmark labels.
v2.26.10 — August 2026
Polished river geometry in Retro River Naval Defense (/naval-defense) to eliminate shoreline pinching: widened turn radii and ensured a minimum 200px vertical buffer between all adjacent river channels across Emerald Delta, Arctic Fjord, and Volcanic Straits for pristine tactical visibility and fortress placement.
v2.26.9 — August 2026
Redesigned and expanded Retro River Naval Defense (/naval-defense) with grand, multi-bend serpentine river systems spanning the entire 1000x800 battlefield: engineered expansive natural meanders that guide warships gracefully downwards, curve through inland archipelago loops, climb along mountain gorges, and navigate across wide coastal delta basins with smooth spline-interpolated ship physics and 360° defensive fortress perches.
v2.26.8 — August 2026
Reorganized river channel layouts in Retro River Naval Defense (/naval-defense) to prevent path overlapping: engineered clean 180px+ vertical and horizontal lane clearances across Emerald Delta, Arctic Fjord, and Volcanic Straits, providing spacious build corridors for coastal fortress placement and unobstructed fleet navigation.
v2.26.7 — August 2026
Extended and elongated river navigation waterways across all 3 battle arenas (Emerald Delta, Arctic Fjord, and Volcanic Straits) in Retro River Naval Defense (/naval-defense), adding sweeping serpentine loops and defensive choke points. Rebalanced enemy warship base speeds by ~35% slower to provide strategic tactical pacing for coastal battery placement.
v2.26.6 — August 2026
Fixed and streamlined Auto-Wave Mode in Retro River Naval Defense (/naval-defense): migrated wave triggers and auto-wave transitions to a reliable delta-countdown engine inside the game physics loop, eliminating stale closures, ensuring instant wave triggers on toggle, and rendering real-time countdown progress.
v2.26.5 — August 2026
Updated defeat mechanics in Retro River Naval Defense (/naval-defense): strictly enforced zero-breach harbor defense rules where a single enemy warship reaching the ocean gate results in an immediate base breach, screen-shaking harbor explosion, and in-canvas game over modal with instant restart capabilities.
v2.26.4 — August 2026
Implemented a dedicated Vector Sprite Rendering Engine for Retro River Naval Defense (/naval-defense): upgraded coastal towers with multi-layered octagonal granite bastions, rotating brushed-steel turret platforms, Level 1-3 visual weapon evolutions, and corner rivet detailing. Overhauled enemy warships with metallic gradient hulls, armored barbettes, deck planking lines, and illuminated radar masts.
v2.26.3 — August 2026
