The Paper Pro doubles as a document reader and markup surface. It ingests PDF and EPUB files, renders them on the Canvas Color panel, and lets you write, highlight, and draw directly on the page in color. Understanding what the device converts, what it reflows, and what it exports is the difference between a smooth reading workflow and one that stalls on large files or loses annotations on the way out.
Importing PDF and EPUB
The device accepts two document formats for import: PDF and EPUB. When you upload through the web interface (my.remarkable.com), the accepted upload types widen to PDF, EPUB, JPG, and PNG, each capped at 100 MB. Files reach the tablet through several channels: the mobile app, the desktop app, the web app, cloud integrations (Google Drive, OneDrive, Dropbox), email, or a direct USB connection. For USB transfer, enable the USB web interface under Settings > Storage, then open 10.11.99.1 in a browser and drag files in. Once transferred, documents sync across every connected device over Wi-Fi.
EPUBs are not read natively. The device converts each EPUB to a PDF for display, so on-screen you are effectively annotating a rendered PDF. Large EPUB conversions can take a noticeable amount of time, and EPUBs land in a dedicated ebook area.
| Direction | Formats | Notes |
|---|---|---|
| Import (device) | PDF, EPUB | EPUB is converted to PDF for display |
| Import (web upload) | PDF, EPUB, JPG, PNG | 100 MB per file limit |
| Export | PDF, SVG, PNG | Annotations flatten into exported PDF |

Annotation and highlighting
Any open document can be annotated. Marks live on a separate layer over the page and can be drawn in color: black, gray, white, blue, red, green, yellow, cyan, and magenta, with orange and pink available on selected tools. Highlighter marks attach to text, so when you use the Select tool to circle and move a passage, the highlight travels with it.
The layer model carries limits. Annotations and highlights are not searchable within the document text, and there is no consolidated highlight view or dedicated highlight-export function. The device also lacks native dictionary lookup, bookmarking, and text-selection handles.
Reading settings and reflow
For reflowable text (EPUB-derived pages), the device exposes six font sizes, three text alignments, adjustable page margins, and adjustable line spacing across six fixed typefaces. There is no paragraph-spacing control. A zoom function exists but resets to default when you turn a page; the crop tool preserves a zoomed view across page transitions.
These controls become limiting on long publications. Because the device re-renders on each change, bumping the font size on a large book can cause significant lag and brief unresponsiveness. The practical workaround is to pre-convert large EPUBs in Calibre to reMarkable PDF page dimensions at a comfortable font size, moving the expensive layout work off the device.
Exporting and emailing
The toolbar's export-and-share button sends documents out as PDF, SVG, or PNG. When you share an annotated document as PDF, the annotations flatten into the file — there is no separate export-highlights-only option. The same button emails documents directly, including annotated PDFs, and offers Convert to Text for handwritten notes. Handwriting conversion runs on-device; a Connect subscription also enables conversion through the desktop app and adds handwriting search, cloud sync, and unlimited storage.
Screen Share and Read on reMarkable
Two features bridge the tablet to the wider workflow. Read on reMarkable is a Chrome-only browser extension that one-click sends web articles to the device. It offers three landing formats: PDF, which preserves the article's visuals and allows margin annotation; EPUB (simplified text), which yields on-device text settings; and Notebook, an editable reMarkable notebook that requires a Connect subscription. The extension works only in Google Chrome and needs a reMarkable account.

Screen Share runs in the opposite direction, mirroring the tablet's screen live to a connected computer for presentations or video calls. Community projects such as goMarkableStream provide alternative streaming paths to a browser tab.
