PlanetOS vs CloudConvert
The main difference: CloudConvert is a website that converts files on its servers, so you upload each file and download the result. PlanetOS is an app that converts files on your own computer, with no upload and no file size limit.

Side by side
- Where files go: CloudConvert uploads them to its servers. PlanetOS keeps them on your computer.
- How you use it: CloudConvert runs in the browser. PlanetOS works from Finder or File Explorer: drag a file, tap Shift, drop it.
- Big files: uploads and downloads take time with CloudConvert, and the free plan has limits. PlanetOS has no size limit and works offline.
- Price: CloudConvert has a free daily allowance and paid packages or subscriptions. PlanetOS has 5 free actions a week and Pro for a one-time $9.99.
- Platforms: CloudConvert works anywhere with a browser, including phones. PlanetOS runs on Mac, Windows and Linux desktops.
When CloudConvert is the better choice
If you're on a phone or a computer where you can't install apps, or you need an API to convert files from your own server, CloudConvert is built for that. It also handles some rarer formats.
For everyday conversions on your own computer (iPhone photos, PDFs, Word files, videos) PlanetOS is quicker because there's no upload step, and nothing leaves your machine.
PlanetOS does all of this on your computer. Your files are never uploaded, and it works without an internet connection.
