Calibre

Calibre is the free desktop program for managing an ebook library, but the reMarkable is not a device it plugs into directly. The Paper Pure has no USB drive mode, and Calibre has no built-in driver for it.

What Calibre is still good for here

• Keeping your master library of EPUBs on your computer, tidy and with clean metadata.
• Converting EPUB to PDF for the Paper Pure, which is often the more reliable format on this device.
• Trimming and resizing PDFs to a page size close to the 10.3-inch screen so they display and annotate well.

How documents get onto the device

• The reMarkable desktop or mobile app — the normal route. Add files there and they sync to the device.
• A community Calibre plugin for the reMarkable can add a “send to reMarkable” action that uploads through your account. It is unofficial and may lag behind firmware, especially on the newer platform the Paper Pure uses.
• Over SSH, if you have enabled developer mode, using “scp” to copy files into the device’s document folder.
