About the Bookmarklet Converter

This tool is designed for developers, SEO specialists, and power users who need to inspect or modify bookmarklets. Bookmarklets are small JavaScript programs stored as a URL within a bookmark. They are often URL-encoded and minified, making them hard to read.

Our Convert Bookmarklets to JavaScript Online tool automatically strips the javascript: protocol, decodes URI components (like %20 to spaces), and optionally formats the code with proper indentation so you can understand exactly what the script does.

How to Use

  • Step 1: Right-click your bookmarklet in your browser's bookmarks bar and select "Edit" to copy the URL.
  • Step 2: Paste the code (starting with javascript:) into the left input box.
  • Step 3: Click "Convert". The tool will instantly decode and beautify the code in the right panel.
  • Step 4: Use the "Copy Result" button to save the clean JavaScript code.

Why Use This Tool?

Unlike other converters, this tool runs entirely in your browser (client-side). Your code is never sent to a server, ensuring 100% privacy. It also features a custom-built "Smart Beautifier" that handles common bookmarklet minification patterns better than standard formatters.
