Use cases

When to use URL Encoder / Decoder

Encode and decode URL components and query values.

1Encode a search term before adding it to a query string
2Decode a redirect URL captured in a log
3Debug Unicode characters in an API request URL
4Compare the text encoding observed by a proxy, gateway, and application service
5Generate or restore an encoding format required by a legacy system
6Diagnose garbled multilingual content and cross-region request data

Guidance

Get reliable results

  1. 1Encode individual values rather than blindly encoding an entire URL
  2. 2Keep the original URL when comparing query semantics
  3. 3Treat plus signs according to the receiving server's rules
The tool follows encodeURIComponent behavior and does not assume every plus sign represents a space.
