Will my AZW3 file work on Kindle, Kobo, and other readers?
+
AZW3 is supported on all major e-readers. Where AZW3 is Kindle-specific (MOBI / AZW3), it works on every Kindle device and the Kindle app on phone or desktop.
Does the converter handle DRM-protected EPUB files?
+
No. PDF.to cannot remove DRM and will refuse protected EPUB files. You must remove DRM legally (e.g. through the original retailer) before conversion.
Will embedded images in the EPUB ebook stay embedded in the AZW3?
Does the AZW3 keep my reading position from the EPUB?
+
No — last-read-position is reader-specific and stored by your device. The AZW3 file itself is just the book; sync your reading position via your reader's cloud.
Can I batch-convert multiple EPUB files to AZW3?
+
Yes — upload a whole library and you will get a ZIP of AZW3 files back, one per book.
Is the EPUB to AZW3 conversion free?
+
Yes, within the free size limit (which covers nearly every ebook). PRO unlocks batch jobs and larger files for image-heavy graphic novels.
Will hyperlinks and footnotes still work in the AZW3?
+
Yes — both internal (cross-chapter) and external (web URL) links are preserved, and footnotes remain tappable / clickable in the resulting AZW3.
What about font and styling differences between EPUB and AZW3?
+
Ebook readers control fonts on the user's device, so AZW3 content uses the reader's preferred font. Inline emphasis (bold, italic, monospace) is preserved.
Are my EPUB ebook files private?
+
Yes. Uploads are encrypted, conversion runs on an isolated worker, and both the EPUB and the resulting AZW3 are deleted within an hour.
