Before you start
Encode or decode a URL component or a whole URL once. Whole URL mode preserves URL delimiters, and decoding + as a space is optional. Malformed percent escapes are rejected; no URL is visited.
How to use this tool
- Paste the URL component or whole URL you need to convert.
- Choose Encode or Decode and the scope. For form-style decoding, enable + as a space.
- Check that separators are preserved in whole URL mode, then copy or download the result.
Supported inputs and limits
Pasted text is limited to 1 MiB; review the result before using it.
Encoding an already percent-encoded value will encode its % signs again; inspect the input before converting.

Frequently asked questions
Are my files uploaded?
No. Files and tool input are processed in your browser. Moving around the site can keep a temporary workspace in the same tab. Refreshing or closing the tab clears it, so download results you want to keep.
What should I check in this result?
