URL Encoder/Decoder is a free online tool that processes everything directly in your browser. URL encoding and decoding stay in your browser; site analytics, ads, or newsletter features may still make normal page requests.
Why URL Encoder/Decoder?
- Client-Side Tool: Encoding and decoding run in your browser after the page loads.
- Free & No Signup: No account needed, no limits, no paywalls.
- Fast & Lightweight: Built for speed with minimal page weight.
- Mobile Friendly: Works perfectly on any device.
What We Cover
The site is focused on practical URL encoding problems: percent-encoding reserved characters,
choosing between encodeURI and encodeURIComponent, building safe query
strings, handling Unicode, and debugging API URLs that break because a delimiter was not encoded.
The guides are written to complement the tool. You can read the rule, paste the example into the encoder, and see the exact output that a browser or API client would send.
