Everyday utilities,
running at the edge.

Convert units, images and PDFs without ever leaving your browser. Instant, private, and free — your files never touch a server.

Length, mass, temperature, data and more. Live, debounced conversion across 60+ units — powered by a ratio-matrix engine.

PNG, JPG, WebP & AVIF with a quality slider and aspect-ratio-locked resizing — processed off the main thread in a Web Worker.

Merge, split and compress PDFs entirely in your browser. Zero uploads, zero accounts, zero privacy trade-offs.

Built for speed & privacy

Pages ship as pure HTML. React loads only where interaction lives — the header toggle weighs kilobytes, not megabytes.

4K images are decoded, resized and re-encoded off the main thread, so the UI never freezes — even on huge files.
