Will my MOBI file work on Kindle, Kobo, and other readers?
+
MOBI is supported on all major e-readers. Where MOBI 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 MOBI?
+
はい、カバー画像、インラインイラスト、章のアート画像は、すべて元の解像度で保存されます。
Does the MOBI keep my reading position from the EPUB?
+
No — last-read-position is reader-specific and stored by your device. The MOBI file itself is just the book; sync your reading position via your reader's cloud.
Can I batch-convert multiple EPUB files to MOBI?
+
Yes — upload a whole library and you will get a ZIP of MOBI files back, one per book.
Is the EPUB to MOBI 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 MOBI?
+
Yes — both internal (cross-chapter) and external (web URL) links are preserved, and footnotes remain tappable / clickable in the resulting MOBI.
What about font and styling differences between EPUB and MOBI?
+
Ebook readers control fonts on the user's device, so MOBI 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 MOBI are deleted within an hour.
