EncoderURL
Encode strings into URL-safe percent-encoded format for use in web addresses, query parameters, and API calls. URLs can only contain a limited set of ASCII characters — spaces, special characters, and non-ASCII text must be encoded to prevent broken links and malformed requests. This tool converts any text into its correctly encoded URL form, ensuring it can be safely included in query strings, path segments, and HTTP requests.

How To Use URL Encoder
- Paste the text or URL component you want to encode into the input field.
- The tool converts every character that is not safe in URLs into its percent-encoded equivalent.
- Spaces become %20, ampersands become %26, and non-ASCII characters are encoded as UTF-8 byte sequences.
- Copy the encoded output for use in your web application, API request, or URL string.
- Test the encoded URL in a browser or API client to verify it resolves correctly.
Frequently Asked Questions
What is URL encoding and why is it needed?
URL encoding (also called percent-encoding) converts characters that are not allowed or have special meaning in URLs into a safe format using a percent sign followed by two hexadecimal digits. For example, a space becomes %20, a forward slash becomes %2F, and an ampersand becomes %26. Without encoding, these characters would either be interpreted as URL structural elements or cause broken links.
What characters need to be URL encoded?
Characters that need encoding in URL query strings and path segments include: spaces, ampersands (&), equals signs (=), plus signs (+), hash characters (#), percent signs (%), and any non-ASCII characters like accented letters or Chinese/Arabic characters. Reserved characters (:, /, ?, #, [, ], @) also need encoding when used as data rather than as URL structure.
What is the difference between URL encoding and Base64 encoding?
URL encoding converts specific special characters to percent-encoded format while leaving safe characters unchanged — the result is still mostly readable text. Base64 encoding converts any binary data into a purely alphanumeric string using a 64-character alphabet — the result is completely different from the original and significantly longer. URL encoding is for making strings URL-safe; Base64 is for encoding binary data in text-safe form.
Should I encode the entire URL or just parts of it?
You should encode individual components of a URL — specifically query parameter values and path segment values — not the entire URL structure. Encoding the whole URL would incorrectly encode the structural characters like ://, /, and ?. Use URL encoding on the values you want to pass as parameters, then assemble the full URL with those encoded values in their correct positions.
What is the difference between encodeURI and encodeURIComponent in JavaScript?
In JavaScript, encodeURI() encodes a full URL and preserves URL structural characters (like ://, /, and ?). encodeURIComponent() encodes a string for use as a single URL component (like a query parameter value) and also encodes /, ?, and & which would have structural meaning in a full URL. For encoding query parameter values, encodeURIComponent() is the correct function to use.
