URL Encoder and Decoder

Component, full URL and form value encoding use different reserved-character rules. This tool converts text only and never requests the supplied URL.

How to use this tool

  1. Paste a component, full URL or form value into the local input.
  2. Choose the mode that matches where the text will be used.
  3. Encode or decode once, then copy, download, swap or clear the result without opening the URL.

Frequently asked questions

Which mode should I use?

Use Component for one query value or path fragment, Full URL to preserve URL separators, and Form value for application/x-www-form-urlencoded text.

Will this visit the URL?

No. The input is treated as text only and is never opened, previewed or requested.
