FAQ

Does the Kobo Libra Colour support EPUB natively?

Yes. The Kobo Libra Colour supports EPUB and EPUB3 natively, along with PDF, MOBI, CBZ/CBR, and more. No conversion is needed for DRM-free EPUB files — simply transfer them to the device via USB or Kobo's wireless options.

What is the difference between Kobo Libra Colour and Kobo Libra 2?

The Kobo Libra Colour adds a Kaleido colour E Ink display and a USB-C stylus for handwritten notes, while retaining the same ergonomic physical page-turn buttons, 7-inch form factor, IPX8 waterproofing, and ComfortLight PRO as the Libra 2.

How do I transfer EPUB files to the Kobo Libra Colour?

Connect via USB-C and drag DRM-free EPUB files into the root folder, or use the Kobo Desktop app to sync your library. Alternatively, enable Dropbox in Kobo settings to sync EPUBs wirelessly, or use the Send to Kobo browser extension to send files from your computer.

Can I use a stylus to annotate EPUBs on the Kobo Libra Colour?

Yes. The Kobo Libra Colour is compatible with USB-C styluses (such as the Kobo Stylus 2) for handwritten annotations directly on the screen. You can also use tap-based highlighting and typed notes via the touchscreen without a stylus.

How do I convert PDFs to EPUB for the Kobo Libra Colour?

Use toolkit.bot to convert your PDF to EPUB. The Libra Colour also reads PDFs natively, but EPUB gives you reflowable text that adapts to the device's font and layout settings, and works better with Kobo's reading features like Kobo Plus, Night Mode, and vocabulary lookup.
