URL Encoder Decoder
Encode URL components, decode query strings, and clean links for API calls, tracking parameters, redirects, and browser tests. The tool runs locally in your browser.
When to use this URL encoder decoder
Use it when query parameters, redirect links, API values, UTM campaigns, webhook URLs, or copied search URLs need to be safely encoded or decoded.
Mode guide
- URL component mode is best for a single query value, path segment, or API parameter.
- Full URL mode preserves slashes, colons, ampersands, equals signs, and other URL structure characters.
- Component decoding converts plus signs into spaces for common query string cleanup.

FAQ
Does this URL encoder upload my links?
No. Encoding and decoding run in your browser.
Should I use component mode or full URL mode?
Use component mode for query values and API parameters. Use full URL mode when you want to preserve the URL structure.
Why does plus become a space when decoding?
Many query strings use plus signs to represent spaces, so component mode handles that common case.
