What I particularly appreciate is that all the operations here are free. I can create PDF files out of my fax files without paying a penny. However, it’s the same quality as other reputable tools.



I started using the tool after my phone failed to open a fax file. I needed to convert it to PDF fast and AltoPDF saved me. Since then I’ve only been using this converter.



Converting fax to PDF files has never been easier for me! The tool’s user-friendly interface speeds up the process. And you can do everything online without any installations!
