URL Encode
Percent-encode text for safe use in a URL — entirely in your browser.
How it works
- Paste text.
- Click Encode.
- Copy the percent-encoded result or download it.
Frequently asked questions
- Is my text sent anywhere?
- No. Encoding happens entirely on your device, using your browser's own encodeURIComponent.
- Which characters get encoded?
- Everything that isn't a letter, digit, or one of - _ . ! ~ * ' ( ) is percent-encoded — including reserved characters like & = / ? #, which is what makes the result safe to use as a single query parameter value.
- Can I open a file instead of pasting?
- Yes, there's an Open file button, or you can paste text directly.
