Encode and decode URLs in one workspace
URL Encoder Decoder converts search URLs, query strings, UTM links, and reserved characters to percent-encoded values or back to readable text. Use it to inspect API requests, redirect URLs, campaign links, and encoded search terms quickly.
Useful For
- Encode URLs with spaces, Unicode, or reserved characters
- Decode query strings and UTM parameters
- Review sensitive query values with tokens and sessions hidden
Good To Know
Custom URLs and query strings are not included in shared links. Example links store only the selected sample name and mode.
Developer Check
Generated code, regexes, meta tags, and config snippets should be treated as drafts and tested again in your runtime, security policy, and deployment environment.
How It Works
Inputs are calculated or converted in the browser whenever possible. Compare important results with the original source before using them. Reviewed on Jul 2, 2026.
URL encoding checks
Input type
- Separate a full URL from a single query value
- Check where spaces, Unicode, and special characters appear
Encoding
- Compare single encoding with double-encoded values
- Review how percent signs and plus signs are handled
Before use
- Test in both browser address bar and API requests
- Remove tokens or personal data before sharing URLs
Yes. Convert spaces, non-English text, special characters, and query values into URL-safe text or decode them back.
Both work, but pasting only the query value is easier when you want to inspect one parameter.
The conversion runs in the browser by default, and entered text is not stored on the server.
