URL Encoder / Decoder

Encode plain text to URL-safe format or decode URL-encoded strings online.

Tip: Use encode when embedding a URL as a query parameter. Use decode to read URL-encoded data from logs or APIs.

About URL Encoder / Decoder

URLs may only contain a limited set of characters. Percent-encoding replaces anything outside that set with a % followed by its hexadecimal byte value, so spaces, ampersands, and non-Latin characters can be carried safely in a query string without breaking the URL structure.

How to use

  1. Paste the URL or query string parameter you need to convert.
  2. Choose encode or decode.
  3. Copy the safe, transport-ready result.

Frequently asked questions

Why does a space become %20 or a plus sign?

Percent-encoding represents a space as %20. In the older form-submission format, spaces became plus signs instead. Both appear in the wild, so decoders usually accept either.

Should I encode the whole URL or just parts of it?

Encode individual values only. Encoding a complete URL would escape the ://, slashes, and question mark that give it structure, leaving it unusable.

Which characters need encoding?

Reserved characters carrying meaning — : / ? # [ ] @ ! $ & ' ( ) * + , ; = — plus spaces and any non-ASCII character.
