URL Encoder/Decoder
Encode or decode URLs and query parameters using standard UTF-8 percent-encoding. Choose full URL or component mode for accurate results.
Use Full URL for complete links. Use Component for query parameter values.

When to use URL encoding
- Building query strings (e.g. search parameters)
- Sending data via GET requests
- Handling special characters in URLs
Practical usage
- Encoding query parameters before sending requests
- Fixing broken URLs with spaces or special characters
- Decoding encoded API responses
Encoding ensures URLs are safely transmitted without misinterpretation by browsers or servers.
How it works
- Encode: Converts unsafe characters to %HH format using UTF-8.
- Decode: Converts percent-encoded text back to readable form.
- Full URL: Preserves reserved URL syntax.
- Component: Encodes everything except A-Z a-z 0-9 - _ . ~.
How to interpret: If a URL contains spaces, symbols, or non-ASCII characters, encoding ensures it is correctly processed by browsers and servers without breaking the request.
Examples
- "hello world" → hello%20world
- "[email protected]" (component) → email%3Dtest%40example.com
When to use this tool
This tool is designed for quick, practical tasks such as everyday calculations, data formatting, or simple conversions. It is best used when you need fast results without installing software or using complex tools.
When to use
- Quick checks or one-time calculations
- Validating or converting data before using it elsewhere
- Simple tasks that do not require advanced software
When not to use

Always review results before using them in important contexts.
About this tool
This tool helps you encode and decode URL components safely. It runs entirely in your browser without sending data to a server.
You can use this tool when handling query parameters or special characters in URLs. The results should be interpreted as a correctly encoded or decoded URL string.
FAQ
- What does a URL encoder do?
It converts unsafe characters in a URL into percent-encoded format (e.g., space becomes %20) so they can be safely transmitted over HTTP.
- What is the difference between encodeURI and encodeURIComponent?
encodeURI is for full URLs and does not encode reserved characters like ?, =, and &. encodeURIComponent encodes almost all non-alphanumeric characters and is suitable for query parameter values.
- Does URL encoding encrypt data?
No. URL encoding is not encryption. It only transforms characters into a safe transport format.
- Which character set is used?
This tool uses UTF-8, which is the standard encoding for modern web URLs.
- Is my data sent to a server?
No. All processing is done locally in your browser.
