How to use URL Encoder/Decoder

  1. 1Choose Encode or Decode, then select URL component, Full URL or Form / query value.
  2. 2Paste the exact value you want to transform and run the conversion.
  3. 3Copy or share the result, or send the output back into the opposite operation to check the round trip.

Useful tips

  • •Use URL component for a single query value, path segment or slug because reserved URL separators are encoded.
  • •Use Full URL when characters such as : / ? & = and # should keep their structural meaning.
  • •Use Form / query value when spaces should become +. A literal plus sign is encoded so decoding can distinguish it from a space.

Frequently asked questions

What is the difference between a full URL and a URL component?

A full URL contains structural separators such as ://, ?, &, = and #. A component is one value inside the URL, so those reserved characters are normally percent-encoded when they are data rather than structure.

Why does form encoding use + for spaces?

HTML form-style URL encoding commonly represents spaces as +. In that mode Wid9et also percent-encodes a literal plus sign so the original value can be recovered correctly.

Is the value uploaded?

No. Encoding and decoding happen locally in your browser and Wid9et does not upload or store the value or result.
