FAQ
What is URL encoding?
URL encoding (percent-encoding) converts non-alphanumeric characters to %XX form, e.g. space to %20, Chinese to UTF-8 bytes like %E4%BD%A0, keeping links safe in transit.
Difference between encode and decode?
Encoding turns text into safe %XX format; decoding restores the original text. Paste content and click URL Encode or URL Decode.
Will my data be uploaded?
No, all encoding and decoding runs locally in your browser.
