Hi Product Hunt! I’m Stefan, a web developer and designer. Every time I worked on client projects, I found myself frustrated by heavy, bloated online tools just to do simple tasks like checking color contrast, generating favicons, or compressing images. Most tools either required sign-ups, had hidden costs, or—worst of all—uploaded sensitive assets to external servers. So, I decided to build a lightweight, privacy-first alternative: Stefan Andres Tools (www.stefan-andres.at/tools). What makes them special? ⚬ 100% Client-Side: Everything runs right inside your browser. No data ever touches a server, keeping your assets private and secure. ⚬ Lightning Fast: No bloat, no ads, no sign-ups. Just open and use. ⚬ Built for Webworkers: Includes a Color Palette & Contrast Checker (WCAG compliance), an Icon/Favicon Generator, and a Web Image Optimizer (WebP/AVIF). I built these for my own daily workflow, but I hope they save you as much time as they save me. I’d love to hear your feedback, feature ideas, or bug reports. Give them a spin and let me know what you think!
