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.
Do I need an account?
No. Open a tool and use it; nothing is saved anywhere, and there is no limit on how many files you process.
Is Fizzdoc made by Smallpdf?
No. Fizzdoc is an independent, open-source project and is not affiliated with or endorsed by Smallpdf. Smallpdf is a trademark of its owner and is named here only to compare.
