Show HN: A fast, privacy-first image converter that runs in browser

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, privacy-safe way to handle images for my personal projects — something lightweight enough to replace desktop tools.

Would love feedback from the community — especially on:

Performance on different browsers/devices
