OnlyJPG – Client-Side PNG/HEIC/AVIF/PDF/etc to JPG▲64
TL;DR: private, in-browser converter that turns pretty much any image file format into standard JPEGs. Everything runs locally. No uploads. This started as a five-minute job and forty hours later... I wanted to convert a HEIC without uploading it anywhere, so I wrestled Emscripten/WebAssembly to run Google's Jpegli inside a Web Worker. Now there's a small UI and it handles a bunch of formats.

A bulk image compression service▲7
Hi, so over the weekend I built a free to use service to compress one or more images using MozJEPG encoding enabled via WASM. It's a static site, all the processing happens on the client side, no file uploads or sign-ups needed! Why?

I made a local image compressor to save you from popups andsubscription▲5
Hey HN. Online image compressors are good, actually not! popups, subscription, clunky ui & more... So I created ConUtil Compressor it's 100% free and opensource. The only local image compressor that doesn't suck or get you into subscription hell. Enjoy! Ahmed
