Why does this exist?

Honestly? I got tired of shady file converter sites. You know the ones — buried behind 47 ads, asking you to sign up for newsletters you don't want, watermarking your files, or just straight up not working.

I just wanted to convert a PNG to JPG without jumping through hoops. Is that too much to ask?

So I built Shift. It's dead simple: drag your files in, pick a format, done. No accounts, no watermarks, your files never leave your computer. The conversion happens entirely in your browser using FFmpeg compiled to WebAssembly.

(Yeah, the converter app itself loads from the internet - obviously - but your actual files? They stay on your device.)

What makes this different?

• Actually free — no "premium tier" hiding the features you need
• Private — your files never leave your computer
• Fast — no uploading to remote servers
• Works offline — once it's loaded, you don't even need internet

Who made this?

Hi, I'm @blazfxx. I run BOXU and build random tools when something annoys me enough. This was one of those times.

The code is open source on GitHub if you want to poke around or suggest improvements. Or just use it and never think about it again — that's cool too.
