What this tool does
Encode reserved characters for URLs or decode percent-encoded strings with selected inputs processed locally in your browser.
Privacy behavior
Selected file contents are processed locally in your browser for supported workflows. This privacy build does not intentionally load ads, analytics, remote fonts, or third-party runtime scripts.
Supported workflow
URL encoding is useful for query strings, API calls, redirects, search parameters, and debugging links that contain spaces, Unicode, or reserved characters.
When should you encode URLs?
URL encoding is useful for query strings, API calls, redirects, search parameters, and debugging links that contain spaces, Unicode, or reserved characters.
Use full URL mode when the URL structure should stay readable. Use component mode when encoding a single query value or path segment.
Frequently Asked Questions
Is this URL Encoder free?
Yes. You can encode, decode, copy, and clear text without signup.
Is my URL uploaded?
No. All URL encoding and decoding happens locally in your browser.
What is the difference between full URL and component mode?
Full URL mode keeps URL separators such as : / ? and & readable. Component mode encodes those reserved characters too.
Does it support Unicode and emojis?
Yes. UTF-8 text, emojis, accents, and non-Latin scripts are supported.
What happens with malformed percent-encoding?
The tool shows a friendly warning and keeps your original input.
