When to use it

Encode or decode URL components, full URIs and form/query text. Handle Unicode and percent escapes explicitly.

Before you export

Component, full-URI and form rules treat reserved characters differently. A plus sign means space in form decoding, not in every URL mode.

How to use this tool

  1. Enter a value and choose component, full-URI or form/query mode.
  2. Run the action and review errors, warnings or validation details.
  3. Copy or download the available result; reset clears the current task.

Questions about this tool

Will it decode an already encoded value repeatedly?

No. Each action performs one pass. Check the result before choosing to run another pass; malformed percent escapes produce an error.

Do my files or text leave this device?
