About URL Encoder / Decoder
URL Encoder & Decoder (Percent-Encoder) safeguards web URLs by encoding special characters into RFC 3986 compliant percent-encoded strings. Reserved characters like spaces, ampersands, question marks, and non-ASCII symbols are converted into safe hexadecimal representation.
Essential for web developers building query strings, deep links, and API request parameters, this tool ensures web browsers and web servers parse your link parameters without broken paths or unexpected errors.
Common Use Cases
- Encoding query parameters containing spaces, ampersands, and accents for web GET requests
- Sanitizing redirects and referral links containing non-ASCII symbols or foreign language scripts
- Decoding percent-encoded URL links from server access logs and analytics paths
How to Use URL Encoder / Decoder
- Choose 'Encode' or 'Decode' mode.
- Paste your target URL string or query parameters into the text area.
- Click 'Process' and copy the RFC 3986 compliant result.

- URL encoding converts reserved characters into %HEX notation; it is not a data encryption method
Privacy & Data Security
URL Encoder / Decoder processes all operations 100% locally in your web browser memory. Your files, text snippets, and generated outputs are never stored, logged, or uploaded to any remote server.
Frequently Asked Questions
URLs can only contain a limited set of ASCII characters. Characters like spaces, ?, &, and non-English scripts must be encoded so web servers understand where parameters begin and end.
encodeURI preserves URL structure (like http:// and slashes), while encodeURIComponent encodes every special character, making it ideal for query parameter values.
Yes, switch to URL Decode mode to convert %20 back to spaces and %26 back to ampersands.
Yes, it implements standard RFC 3986 percent-encoding for full compatibility across modern browsers and backend servers.
