URL encode or decode text

Percent-encode text so it can sit safely inside a link, or decode a URL full of %20 and %26 back into readable text. Value mode encodes a single query parameter. Whole-URL mode keeps the :, /, ?, # and & that a link needs. Use it to build query strings, read tracking links, or debug redirects. Everything runs in your browser.

Common URL codes

Character Encoded
space %20
& %26
/ %2F
? %3F
= %3D
# %23
₹ %E2%82%B9

Tips

  • Encode each query value on its own, then join them with &.
  • Decode only once. Decoding twice can turn a real % into the wrong character.
  • Making a QR code for the link? Encode it first, then use the QR code generator.

For tokens and data fields, use the Base64 encoder. To check a JSON payload, use the JSON formatter.

Frequently asked questions

What is URL encoding?

Replacing characters that aren’t allowed in a URL with % and two hex digits. A space becomes %20, & becomes %26 and / in a value becomes %2F.

Value mode or whole-URL mode?

Use value mode for a single query parameter, where almost everything is encoded. Use whole-URL mode for a full link, which keeps : / ? # and & so the link still works.

Why is a space %20 and not +?

This page follows encodeURIComponent, which uses %20. HTML forms use + for spaces. Replace + with spaces before decoding form data.

Why does decoding fail?

Each % must be followed by two hex digits. A stray % or a cut-off sequence can’t be decoded.

Is the link opened or sent anywhere?

No. The text is transformed in this tab and never requested.
