FAQs
What is the difference between the two encode modes?
encodeURIComponent escapes almost every character and is meant for single query values, while encodeURI keeps characters like slashes and colons intact for full URLs.
Why do spaces become %20?
URLs can only contain a limited set of characters. Encoding converts characters like spaces into percent-encoded forms such as %20 so they travel safely.
Do I need to encode my URLs manually?
No, most programming languages handle this for you, but this tool is handy for debugging, building query strings by hand, or testing edge cases.
Is the URL data sent anywhere?
No. Encoding and decoding happen entirely in your browser, so nothing you paste is uploaded or logged.

Why encode a URL?
URLs can only contain a limited character set, so special characters must be percent-encoded to travel safely. Encoding keeps query parameters intact when building links, forms or API calls.
- Encode query parameters safely before building an API request.
- Escape user input to prevent broken links or malformed URLs.
- Decode an encoded URL to read what it actually points to.
Tips and Limits
Use encodeURIComponent for single query values and encodeURI for whole URLs — they escape different character sets. Everything runs locally, so your data never leaves the browser.
