URL Encoder & Decoder
URL encoding (percent-encoding) converts characters that aren't allowed in a URL — spaces, &, ?, non-ASCII characters — into a safe %XX format. This tool converts either direction instantly.
Frequently Asked Questions
- Why does a space become %20 or +?
- %20 is standard percent-encoding; + is a convention specific to query strings and form data.
- Do I need to encode an entire URL or just parameters?
- Usually only individual parameter values need encoding, not the full URL structure.
