About URL Percent Encoding

URL percent encoding (also known as URL encoding or percent-encoding) is a mechanism for encoding information in a URL. This tool helps you:

  • Encode text to URL-safe percent format (%20 for space, %26 for &, etc.)
  • Decode percent-encoded URLs back to plain text
  • Handle special characters and spaces in URLs
  • Test API parameters and query strings
  • Prepare data for web transmission

Common encoded characters include: space (%20), ! (%21), # (%23), $ (%24), & (%26), ' (%27), ( (%28), ) (%29), * (%2A), + (%2B), / (%2F), : (%3A), ; (%3B), ? (%3F), @ (%40), [ (%5B), ] (%5D), and many more.
