Frequently asked questions

Is PDF Cloak a good PDF24 alternative?

If you're on Windows and happy installing software, PDF24's desktop app is a solid local option. If you're on a Mac, Linux, or mobile — or don't want to install anything — PDF Cloak gives you local processing in any browser, without the ads.

Are PDF24's online tools private?

PDF24's online tools upload files to their servers for processing, with deletion shortly after. The company is German and subject to EU data law, which is better than average — but the files still leave your device. PDF Cloak's tools never transmit your files at all.

How can both tools be free?

PDF24 funds itself with ads on its website. PDF Cloak has near-zero running costs because your device does the processing, so there are no ads, no trackers, and no analytics scripts — and we plan to monetize later with optional capabilities, not your data.
