Hey Product Hunt! 👋 I built OnlineImageTools because I was tired of uploading my private photos to random servers just to resize or convert them. The turning point: my friend sent me her iPhone photos to convert from HEIC to JPG, and I realized most "free online tools" upload your files to process them server-side. That's when I decided to do everything in the browser instead. How it works: → Canvas API for image processing → File API for local file access → Web Workers for background processing → Your files NEVER leave your device The site has 8 tools: Resizer, HEIC→JPG, Compressor, WebP→PNG, SVG→PNG, Bulk Resizer, Format Converter, and Background Remover. Plus 15 blog posts with image editing guides. Tech: Next.js 16 + TypeScript + Tailwind + Vercel. Would love your feedback! Which tool would you use most? 🙏
