URL Encoder
Runs entirely in your browser
Percent-encode text directly in your browser so it's safe to use inside a URL or query string.
Off encodes a single value with encodeURIComponent. On also escapes URL-structural characters with encodeURI-style full encoding — use this only when encoding an entire URL isn't your goal.
What is URL Encoder?
URL Encoder (percent-encoding) replaces characters that aren't safe inside a URL — spaces, &, =, ? and others — with a % followed by their hex code. This lets arbitrary text travel safely as part of a URL or query string.
How to use URL Encoder
- Type or paste your text into the Input box.
- Click Encode.
- Copy the percent-encoded result from the Output box.
Features
- Encodes query-parameter values safely with
encodeURIComponent. - Optional full encoding for reserved URL characters.
- 100% client-side — your text never leaves your browser.
Frequently Asked Questions
Is my text uploaded to a server?
No. URL Encoder runs entirely in your browser. Your text never leaves your device.
What does URL encoding do?
It replaces characters that aren't safe inside a URL — spaces, &, =, ? and others — with a percent sign followed by their hex code, so the value can travel safely inside a URL or query string.
Should I encode a whole URL or just part of it?
Encode individual query parameter values, not an entire URL — encoding a full URL would also escape characters like : and / that need to stay intact for it to work.
What's the difference between this and Base64 encoding?
URL encoding (percent-encoding) makes text safe inside URLs; Base64 encoding makes arbitrary binary data safe inside plain text. They solve different problems and aren't interchangeable.
