It also fits anyone who wants to avoid sign-ups, watermarks and daily limits. Very large files are limited by the memory of the device, since all processing is local.

It fits people who need annotated reading or exports to Word and PDF. It runs only in Chrome and Edge, so users of other browsers are not covered.
