URL Encode and Decode

About this tool

Percent-encode text for use in a URL, or decode it back. Component mode encodes everything except letters, digits and a few marks, which is right for a single query value. Full URL mode leaves characters such as / ? & = # alone so the URL keeps its shape.

When decoding, a malformed sequence such as a lone % is reported as an error. Form-encoded text uses + for a space; turn on the option to decode it that way. Input is limited to 1 MB.

How to use it

1. Paste the text or URL.
2. Choose component mode for a single query value, or full URL mode to keep / ? & = # as they are.
3. Encode or decode and copy the result.

Example

Input:

Ada Lovelace & São Paulo

Component mode:

Ada%20Lovelace%20%26%20S%C3%A3o%20Paulo
