Smallpdf alternative: private PDF tools that never upload your files
Smallpdf is a well-known, polished suite of PDF tools. If you mostly care about keeping documents on your own device, or you want a simple browser tool without an account, Intelli File is built for that. If you need Office conversions or a desktop app, Smallpdf may suit you better. Here is how they differ.
