ToolFusion — Browser-Based Media Editor

The challenge

Media tools are easy to prototype and hard to ship at scale. Users expect instant uploads, fast transforms, and downloads that work on mobile networks. Heavy client bundles and blocking third-party scripts destroy Core Web Vitals on exactly the pages that need speed most. We wanted a utility site that felt native-fast without asking users to install anything.

Our solution

ToolFusion runs as a React + Vite front end with API-backed processing, assets served through Cloudflare, and analytics loaded after idle so LCP stays clean. The UX is task-first: pick a tool, drop a file, get a result — no account required for core flows.

How we approached it

• We split tools into lazy-loaded routes so visitors only download the code for the editor they use.
• Critical CSS is inlined for above-the-fold shells; GA4 loads on lazyOnload.
• Cloudflare caching rules cover static assets and safe API responses where appropriate.

Results

• Live production tool at toolfusion.org
• GIF, image, and video workflows in one product surface
• GA4 tracking with deferred load for better Core Web Vitals
• Cloudflare CDN delivery for global performance
