MediaForge

I built a free browser tool that converts images, videos

What it does

Hey! I've been working on a side project called MediaForge. It's a web app that lets you: - Play any video format (MKV, AVI, WMV, FLV, etc.) - Convert between 30+ formats (images, videos, audio) - Everything runs locally in your browser using WebAssembly The main thing I wanted to solve was privacy — most converter sites upload your files to their servers. This one processes everything on your device. Nothing ever leaves your browser.

Does the same job

I built image converters site that run in the browser2024 · dynapik.com · ▲19
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,
