About ConverterUp

ConverterUp is a small toolkit of free converters that run entirely in your browser. No uploads, no accounts, no servers handling your files.

Why client-side?

Most online converters upload your files to a remote server, queue them behind paid plans, and may keep them long after you're done. We wanted the opposite: open the page, drop a file, get the result, close the tab. Your files never leave your device.

How it works

Under the hood we use ffmpeg.wasm for video and image conversion, and standard browser APIs (Canvas, Web Crypto, FileReader) for everything else. Performance is bound by your hardware, not by our servers.

How we keep it free

We display unobtrusive ads through Google AdSense to cover the hosting and domain costs. There is no paid plan, no "upgrade" modal, and no premium features behind a wall.
