Encode and decode URL components safely. Perfect for web development and API integration.
Encoded result will appear here...
URL encoding, also called percent-encoding, replaces characters that have special meaning in a URL with a percent sign followed by two hex digits. A URL encoder converts text into a safe form for query strings, form submissions, and API calls, and a decoder reverses the process to read the original value. Developers use it constantly when debugging requests, parsing webhooks, or building links with parameters that contain spaces, slashes, or international characters.
Drop in the raw string, query parameter value, or encoded URL you want to convert.
Choose encode to turn plain text into percent-encoded form, or decode to read an encoded string back to its original.
encodeURIComponent encodes everything including slashes and ampersands, while encodeURI preserves URL structure characters.
The result updates as you type so you can confirm the conversion looks correct.
Click copy to send the encoded or decoded string to your clipboard for use in code, a browser, or an API client.
encodeURI leaves characters like /, ?, &, and = alone because they have meaning in a URL. encodeURIComponent encodes those too, which is what you want when the string is a single query parameter value.
Both are valid in different contexts. %20 is the standard percent-encoded space for URL paths, and + is the form-encoded space used in application/x-www-form-urlencoded request bodies and query strings.
Yes. Run the decoder once and check the output. If you still see percent signs followed by hex digits, decode again until the string is fully readable.
No. Encoding and decoding happen entirely in your browser, so sensitive query strings, tokens, and webhook payloads never leave your device.
Encode each value separately with encodeURIComponent, then join them with ampersands. For example, name=John%20Doe&city=S%C3%A3o%20Paulo keeps each value safely escaped.
The string was likely encoded in a different character set than UTF-8, or it was double encoded. Try decoding twice, or check the source system for its expected charset.
