Frequently asked questions

Will my PDF's layout reflow properly in AZW3?

Text-based PDFs with simple, single-column layouts reflow cleanly to fit any Kindle screen. PDFs with multi-column text, dense tables, or heavy graphic design can end up with awkward spacing or images that don't resize well, since AZW3 is built for flowing text rather than fixed pages.

Do I need an account or a subscription?

Universal PDF requires a Pro subscription. One subscription unlocks every tool on the site, cancel anytime.

Does this work on DRM-protected ebook PDFs?

No. DRM-protected files can't be converted by this or any online tool. The protection specifically blocks that. This converter is for PDFs you have full rights to convert, such as your own documents or DRM-free ebooks.

What about scanned PDFs?

AZW3 conversion needs selectable text to reflow. If your PDF is a scan or a photo of a page, run it through the OCR PDF tool first to recognize the text, then convert the result to AZW3.
