What this conversion does

Encode special characters into percent-encoding or decode percent-encoded URLs back to readable text.

Practical workflow

Paste your URL, query string, or plain text into the input field.
Choose 'Encode' (encodeURI / encodeURIComponent) or 'Decode' mode.
Copy the resulting escaped or unescaped string.

Common use cases

Encode query parameters containing spaces, ampersands (&), and non-ASCII characters.
Decode obscure percent-encoded tracking links and redirect URLs (e.g. %20, %2F, %3F).
Sanitize web hook payloads and REST API endpoints.

Important notes and limitations

Standard RFC 3986 percent-encoding replaces unsafe ASCII characters with '%' followed by two hexadecimal digits.
Spaces can be represented as '%20' or '+' depending on form-urlencoded specifications.

Frequently asked questions

What is the difference between encodeURI and encodeURIComponent?

encodeURI preserves protocol and domain characters (like :, /, ?), while encodeURIComponent encodes everything, making it suitable for single query parameter values.

How are international UTF-8 characters encoded in URLs?

Unicode characters outside the ASCII range are converted into UTF-8 bytes and represented as multiple percent-encoded triplets (e.g. 'é' becomes '%C3%A9').
