How to use URL encode and decode

  1. Paste your text or URL.
  2. Tick Whole URL if you're encoding a complete address.
  3. Press Encode or Decode and copy.

Questions

When should I tick Whole URL?

When encoding a full address: it keeps characters like : / ? & = intact. Leave it off to encode a single query value.

Why is a space sometimes + and sometimes %20?

Form submissions encode spaces as +, while URLs use %20. Decoding treats + as a space when that option is ticked.
