Hey Product Hunt! I built TinyTool because I was annoyed by the existing options. Every time I needed to compress an image or merge PDFs, I'd land on a site that wanted me to upload my files to their server, create an account, or pay for basic operations. TinyTool is the opposite: - Everything runs in your browser — your files never leave your device - 40+ tools across 7 categories — image, PDF, text, dev, converters, generators, social - Zero friction — no sign-up, no waiting, no server round-trips Some tools I'm especially proud of: - PDF merge/split that handles 100+ page documents client-side - Code-to-image generator with syntax highlighting themes - Ethereum keypair generator using @noble/secp256k1 The site is open to everyone — not just developers. My mom uses the image compressor and PDF tools, my designer friends use the color converter, and I use the dev tools daily. What tools are missing? I can probably add them this weekend.
