What URL Encoder does
Percent-encoding represents reserved and non-ASCII characters safely inside URLs. Choose component encoding for query values and full decoding for inspection.
Common uses
- Encode a query parameter
- Decode redirect URLs from logs
- Inspect Unicode URL values
Privacy and limitations
No URL is requested and no input is transmitted. This tool only transforms text locally.
Always validate security-sensitive output in the authoritative application or platform.
Frequently asked questions
Should I encode a full URL?
Usually encode individual query values with encodeURIComponent rather than encoding the entire URL.
Why are spaces encoded as %20?
Percent-encoding uses %20. HTML form encoding may use + instead.
