Great work, AltoPDF! I’ve tried a dozen of PDF document management platforms, both paid and free, and none of them beats this one. It’s simple, accurate and secure. Switching between PDF and other popular document formats have never been this easy!



I simply love this app. It contains a whole bunch of online converters as well as a web-based editor for quick and painless document processing. With AltoPDF, I’m able to compete all kinds of PDF-related operations with a flick of my finger.



I would strongly recommend AltoPDF to anyone who seeks a simple solution for processing PDF documents online. I’ve been using it for a while and never have I had any problem converting and redacting my files.



I’ve been using AltoPDF for a long time now. Primarily, I use the app to convert files to PDF but it’s also capable of performing many other useful operations. What I love about the app is that it’s simple and precise. I’d rate it 5 out of 5.



I had a great experience processing my docs via AltoPDF and will definitely keep using the service in future. I think it deserves the highest ranking - because of its simple interface and because it works equally good on any device you have.



AltoPDF was a huge sigh of relief for me. I found it much more accurate and efficient than all those downloadable apps you see on the Internet. It may look simple but it’s actually much more than just another PDF converter.



Usually I use AltoPDF to password-protect my documents. I prefer this platform because it’s trustworthy and convenient. Which AltoPDF, I know that my data is one hundred percent secure and cannot be compromised. Great service. No complains at all!



AltoPDF is my first choice whenever I need to convert a file to and from PDF. What I like the most is that it’s both very simple and powerful. Even my grandmother could use it!



I’ve used a few PDF platforms before, both paid and free, downloadable and web-based, and I think that AltoPDF is one of the best out there. First, it’s free. Second, it’s really fast. Finally, it’s secure and doesn’t contain any ads.
