Pressbooks

Open source book production built on WordPress, and the default tool for open textbooks

As of 31 August 2026, Pressbooks is free to use. GPL-licensed publishing software that outputs a web book, EPUB and print PDF from one source. Softwr lists it under Publishing. Pressbooks is made by Book Oven Inc., available on Web, Self-hosted.

Overview

What Pressbooks does

Pressbooks is book production software built on WordPress, developed by Book Oven Inc. in Montreal and released under the GPL. An author or institution writes in a familiar web editor and publishes simultaneously as a browsable web book, an EPUB, and a PDF laid out for print, all from a single source. Interactive exercises can be embedded through H5P, and the hosted institutional product connects to Canvas, Moodle and Blackboard through LTI so a book behaves like course content. Its position in open educational resources is what makes it hard to substitute. A textbook published in Pressbooks under an open licence can be cloned wholesale into another institution network, then edited to suit a different course, a different jurisdiction or a different set of examples, with attribution preserved. That workflow is why provincial and state consortia standardised on it, and why the catalogue of adaptable open textbooks that exists in Pressbooks has no equivalent in any commercial authoring tool. For a university library trying to remove a hundred-dollar textbook from a syllabus, the ability to adapt rather than write from scratch is the entire business case. The licence means an institution can self-host and pay no fee, but that comes with an important caveat: the print PDF export depends on a commercial rendering engine whose licence most self-hosters do not buy, so free self-hosting in practice means a web book and an EPUB, with print output degraded or watermarked. Add WordPress multisite administration, upgrades and backups, and the hosted institutional network often turns out cheaper than running it yourself. It is not a trade publishing tool: there is no distribution, no ISBN service and no retail channel.

What people use it for

  • A university library replacing a commercial textbook by adapting an existing open textbook rather than commissioning a new one
  • A course team that wants readings delivered inside Canvas or Moodle with embedded exercises rather than as a static PDF
  • A research institute publishing reports that must exist as a web page, an EPUB and a printable document without maintaining three files
  • A consortium standardising open textbook production across several institutions with a shared catalogue of adaptable titles

The honest half

Where it falls short

Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Pressbooks.

  • Self-hosting is free in licence terms only; it requires WordPress multisite administration, upgrades and backups, which is a real staff cost most institutions underestimate.
  • Professional print PDF output depends on a commercial rendering engine that is licensed separately, so the genuinely free self-hosted route produces web and EPUB output but not press-quality print.
  • Design control is limited to the supplied themes unless someone writes custom CSS, so books tend to look recognisably like Pressbooks books.
  • There is no distribution, no ISBN service and no retail channel, so it produces files and web pages but plays no part in selling anything.
  • The editing experience inherits WordPress conventions, and authors working on long or heavily structured manuscripts find it slower than a dedicated writing application.

Answered, with sources

Questions people ask

Each answer names the page it came from, so you can check it rather than take our word for it.

Is Pressbooks really free?

The software is GPL licensed and free to self-host. The hosted service is priced, and professional print PDF output requires a commercially licensed renderer, so budget accordingly.

Can I sell a book made in Pressbooks?

You can sell the EPUB or the printed book through any distributor, but Pressbooks itself provides no ISBN, no storefront and no distribution.

Why do universities use it for open textbooks?

Because an openly licensed book can be cloned into another institution network and adapted for a different course, which turns a finished textbook into a starting point rather than a fixed artefact.
