I built image converters site that run in the browser
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,
I built image converters site that run in the browser launched on August 29, 2024 with 19 votes, #1,011 of 5,471 launches that month and more than 75% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
This is a browser-based image converter website that processes files locally on the user's device rather than uploading them to external servers. Created to address privacy concerns with traditional image conversion tools, it offers image conversion functionality at no cost. The conversion happens entirely within the browser, meaning users retain full control over their files and no data is transmitted elsewhere.

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…
A fast, privacy-first image converter that runs in browserOct 2025 · imageconverter.dev · ▲48Hey 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 there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
