Working with PDFs and Colour Illustrations

PDF reflow: PocketBook's built-in PDF reflow mode extracts text for reflowable reading, though quality varies with complex layouts. For best results, convert PDFs to EPUB first using toolkit.bot.
Colour illustrations: The Kaleido screen renders colour at lower resolution than the text layer — ideal for charts, diagrams, and covers, but not for photographic images.
Annotation export: Highlights and notes export as .txt or .html via PocketBook Cloud or USB for integration with note-taking tools.
Font customisation: Adjust font family, size, line spacing, and margins independently for each book — useful for dense academic EPUBs.

FAQ

Does the PocketBook InkPad Color support EPUB natively?

Yes. The PocketBook InkPad Color supports EPUB and EPUB3 natively, along with PDF, FB2, DJVU, DOCX, and many other formats. No conversion is required to read EPUB files — simply transfer them to the device.

What is the best way to transfer EPUB files to the PocketBook InkPad Color?

Connect the InkPad Color via USB and drag EPUB files to the Books folder, or use the PocketBook Cloud to sync files wirelessly across your devices. You can also use the built-in Wi-Fi browser to download EPUBs directly from the web or Dropbox integration.

How does the InkPad Color handle colour-illustrated EPUB files?

The InkPad Color uses a Kaleido colour E Ink screen that displays colour at around 100 ppi for colour elements, while maintaining 300 ppi for black-and-white text. It is excellent for illustrated non-fiction, textbooks, and comic EPUBs, though colours appear more muted than on a tablet.

How do I convert a PDF to EPUB for the PocketBook InkPad Color?

Use toolkit.bot to convert your PDF to EPUB. The InkPad Color also reads PDFs natively with pan/zoom and reflow mode, but EPUB gives reflowable text that adapts to any font size, which is especially useful for long academic or professional documents.
