Frequently Asked Questions

What's the difference between the free and Pro versions of Drawboard PDF?

The free version of Drawboard PDF, Basic, includes all the essential tools for viewing and marking up PDFs. It’s great for occasional reading, highlighting, and basic annotation.

Pro Lite works well for occasional PDF annotators, like students who have a few group projects per semester or professionals who review documents from time to time. It adds advanced ink tools, hyperlinks, audio notes, and more cloud syncing.

Pro Plus is for regular users and professionals who rely on PDFs as part of their workflows, such as designers, engineers, educators, or researchers. It includes measurement tools, templates, and redaction to support more advanced workflows.

Pro Unlimited is built for power users and small teams who need everything Drawboard PDF offers. With unlimited sync, Teams integration, and premium support, it’s ideal for those managing multiple files, collaborators, or projects at once.

Will my edits sync across my iPhone, iPad, and Mac?
