Hi everyone, I build some "online" converters as a side project in the last weeks. The difference to existing conversion websites is, that my converters don't upload your files. Everything happens in your browser on your device (with the help of a lot of great Open Source Javascript libraries). I think privacy is an essential feature for a service like this, so my converters also don't use google analytics or any other form of tracking (in fact they use no external resources at all). I started this because I ended up with some .heic files from my iPhone and had to use ImageMagick every time…

Hello HN, I've used a lot of image converter websites to run for my daily jobs, but they required uploading my assets on their servers which I didn't like. I decided to build it myself and publish as a website for everyone to use at no cost (since the conversion happened on your browsers) I'd live to hear your thoughts about it. Cheers,

Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions. So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy. What it does Convert images between JPG, PNG, WebP Works offline once loaded (PWA support) How it works It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices. Why I built it I wanted an instant, no-ads,…

Hey HN! I made How to Convert. Here's the problem I had and the solution I thought of: Problem When you search "How to convert PNG to ICO" on Google, you get a bunch of shady looking "free" results that send your data to unknown servers. The same is true for almost any conversion you are trying to do. So what do I want? I want something I can trust completely. AKA locally running, doesn't send my files or data anywhere and built by an independent developer building in public. Solution How to Convert Privacy-first: Files stay on your device and it works offline. Wide compatibility: Works with…
