Encode or decode strings to make them URL-safe. Instantly translates special characters into percent-encoding and back.

About URL Encoder / Decoder

URL Encoder / Decoder is a simple but essential tool designed to safely translate strings into percent-encoded formats, or decode them back into human-readable text.

How it works

URLs can only contain certain safe characters. When you have spaces, emoji, or symbols like &, =, and ? in your data, they must be translated into a valid ASCII format. For example, a space becomes %20. This tool performs that exact translation securely in your browser.

When to use it

  • Passing complex data through a URL query string parameter.
  • Fixing broken links caused by unescaped spaces or symbols.
  • Extracting human-readable text from messy, percent-encoded analytics parameters.
