Hey Product Hunt! 👋 I built jpegxlconvert.com because every "free" image converter I found either made me sign up, slapped a watermark on the result, or — worst of all — uploaded my private photos to some server I don't control. So I made the opposite: 🔒 100% private — files never leave your browser (everything runs locally via WebAssembly) ⚡ Fast — no upload/download round-trip, conversion happens on your device 🆓 Genuinely free — no sign-up, no watermark, no file-size limits 🖼️ Handles JPEG XL (JXL), HEIC, PNG, JPG & WebP, in any direction 👀 Built-in JXL viewer so you can actually open .jxl files (browsers still can't) JPEG XL is an amazing format that barely any tool supports yet, and HEIC from iPhones is a constant headache — I wanted one place to deal with both without giving up my privacy. It's live and free to use right now. Would love your feedback — especially which formats or features you'd want next. Thanks for checking it out! 🙏
