URL Decoder
Decode percent-encoded URLs and query strings to readable text.
About URL Decoder
URL Decoder reverses percent-encoding, turning %20 back into a space and %E2%82%AC into €. It also handles values where + was used for spaces in form bodies.
Double-encoded strings are common after a redirect chain; decode twice if the first pass still leaves % sequences.
How to use URL Decoder
- 1
Paste the encoded value
A query value, path segment or full URL.
- 2
Choose plus handling
Enable it for application/x-www-form-urlencoded data, disable it for paths.
- 3
Copy the result
Check for remaining % signs, which indicate a second encoding layer.
Questions about URL Decoder
Why does + become a space?
HTML form encoding uses + for spaces. In a path, + is a literal plus, so the option matters.
What is double encoding?
A value encoded twice shows as %2520. Decoding once yields %20, twice yields a space.
Does it handle Unicode?
Yes, percent-encoded UTF-8 bytes are decoded back to characters.
Is my input uploaded?
No, decoding is local.
