UTM Link Builder

UTM Link Builder is a simple, focused tool that helps you create clean, properly encoded URLs with UTM parameters—fast. Specify your source, medium, campaign, term, and content, and the extension assembles a standards-compliant tracking link you can copy in one click. It’s designed for marketers, analysts, and anyone who needs reliable attribution without manual mistakes or broken encoding. Built with a lightweight popup and minimal permissions, it runs locally in your browser and never uploads your data. The extension can optionally remember your most recent inputs (e.g., default source/medium or common campaign tags) so you don’t have to retype them every time, helping teams maintain consistent naming conventions at speed. Clear labels, validation to prevent empty or malformed parameters, and automatic URL encoding ensure your links work across ads, social posts, newsletters, and partner placements. No fluff—just accurate UTM links you can trust to measure performance.
