Frequently Asked Questions
Absolutely not. Unlike typical online converters, AllThatConverter uses WebAssembly and local JavaScript. All processing happens inside your browser sandbox on your computer. Your files never cross the network.
Since processing runs locally on your device, there are no artificial bandwidth or server-side caps. You can convert files without limit, though extreme file sizes (like several gigabytes) depend on your device's RAM capacity.
No registration, no emails, no ads, and no installations are required. It is 100% free, accessible instantly from any mobile, tablet, or PC browser.
