imgformats is a toolkit to convert, compress, and resize images — directly in your browser. No uploads, no sign-ups, no watermarks, no daily limits. Every tool runs entirely on your device using client-side processing, so your images never touch a server. Supports JPG, PNG, WEBP, AVIF, HEIC, GIF, BMP, and more — including bulk conversion and instant HEIC-to-JPG conversion for iPhone photos that won't open elsewhere. Built for the moment you just need a quick image fix, with nothing to install.

Hey Product Hunt! 👋 I built imgformats because I was tired of every "free" image tool wanting me to upload my photos to some random server first — just to convert a PNG to WEBP or compress a JPG for a form. So imgformats does the opposite: everything runs locally in your browser. Your images never leave your device, there's no sign-up, no watermark, and no daily limit. Right now it handles: 🔄 Converting between JPG, PNG, WEBP, AVIF, HEIC, GIF, BMP and more 📦 Compressing images with an adjustable quality slider 📐 Resizing to exact dimensions or common presets Would love your feedback — especially if you hit any bugs or have a format/feature request. Thanks for checking it out! 🙏
