Most "free online tools" aren't really free. They upload your files to their servers, impose size limits, slap on watermarks, or eventually push you toward a paid plan. Werkr is built differently.
Werkr gives you 180+ professional-grade tools that run entirely in your browser. Your images, PDFs, and code never leave your device. There's no account to create, no email to verify, and no feature locked behind a paywall. It also works offline after the first visit, thanks to a service worker that caches the app locally.
