Supported formats of PDFs

PDFs are one of the most frequently used computer files. Nowadays, a lot of devices are used for document presentation, so there are plenty of proprietary and open file formats. The PDF Editor handles the most popular of them.

While uploading or opening the file for editing, it will be converted to the Office Open XML format. It's done to speed up the file processing and increase the interoperability.
