Frequently asked questions
How can Fizzdoc work without uploading my file?
Every tool runs inside your browser tab, using engines compiled to WebAssembly. Your file is read from your device, processed there and saved back to it. The page is only allowed to talk to fizzdoc.com, which serves nothing but the website itself, and you can watch your browser’s Network tab to see that no file leaves.
Why not just install PDF24 Creator?
If you can install software on Windows, it is a good offline option. Fizzdoc is for the times you can’t: office or school computers, Macs, Linux and phones, with nothing to install.
Is Fizzdoc made by PDF24?
No. Fizzdoc is an independent, open-source project and is not affiliated with or endorsed by PDF24. PDF24 is a trademark of its owner and is named here only to compare.
