What is URL Encoding & Why It Matters

This PRO MAX tool encodes and decodes URL components safely using encodeURIComponent and decodeURIComponent standards, with advanced developer options, history, and accessibility features. Use it for preparing UTM links, API requests, or decoding query strings.

How to use

  1. Paste text or an encoded string into the input box
  2. Choose Encode / Decode or Auto-Detect
  3. Use Developer Mode to toggle '+' handling or preserve slashes
  4. Copy, Download, or Share the result

Advanced notes (developer)

By default, slashes (/) are encoded in component encoding; enable "preserve slashes" to keep them. Treating '+' as space helps when decoding application/x-www-form-urlencoded payloads.
