Support

Frequently asked questions

Can I decode a full URL at once?
You can paste encoded components or full query strings. Decoding an entire URL with scheme and domain may require decoding individual parts separately.
What if decoding fails?
Malformed percent sequences trigger an error explaining which part of the input could not be decoded.
Does it handle plus signs as spaces?
In form-encoded contexts, plus signs are treated as spaces. The tool supports standard URI component decoding.
