Free URL encoder and decoder
Turn spaces and symbols into the %20 codes web addresses need, or turn them back into plain text. Paste a long link and see it split into its parts.

Why web addresses need encoding
An address is only allowed a small set of plain characters. A space, an accented letter, an emoji, or a symbol that already means something (&, =, ?, #) would confuse a browser or a server, so it is written as a percent sign followed by its code. Decoding turns the codes back into readable text.
- Search terms and tracking tags in a link are the usual reason to encode.
- Long links full of utm_ tags become readable once they are split into a table of parameters.
- Redirects that carry an address inside an address need the inner one encoded. After fixing yours, check them with our redirect checker.

Questions people ask
What is URL encoding?
Web addresses can only contain a limited set of characters. Anything else, such as a space, an accent or a symbol like &, is replaced by a percent sign and a code. A space becomes %20, and é becomes %C3%A9.
What is the difference between the three kinds?
"One value" encodes everything that has a special meaning in an address, including / ? & = and #, so it is safe to put inside a link, for example a search term. "A whole web address" leaves those alone so the address keeps its shape. "Form data" is the same as one value but writes a space as +, which is how an HTML form sends it.
Why does decoding say a % code is not valid?
A % must be followed by exactly two letters or numbers, like %20. A lone % (as in 100% sure) or a code cut off at the end cannot be decoded. The red box points to the piece that is wrong.
Should I encode the whole link or just the parts?
Encode the parts, then join them. If you encode a whole address as one value, the colon and slashes are encoded too and the link stops working.
Is my data safe?
Yes. It all runs in your browser. Nothing you paste is sent anywhere.
