How to convert PDF to MOBI
- Add your .PDF file - drop it in the box above or click to browse.
- Convert it to .MOBI in a few seconds.
- Download your new .MOBI file.
What to expect
- Fixed PDF layout is reflowed; columns, tables and precise positioning often break.
- Scanned/image-only PDFs need OCR first or the MOBI will contain no real text.
- Amazon retired MOBI in 2022, so EPUB is the better modern target for Kindle.
Frequently asked questions
How faithful is the converted book?
Calibre extracts and reflows the PDF's text into MOBI. Plain prose converts fairly well, but fixed layouts, columns, tables and image placement frequently come out reordered because PDF is page-based and MOBI is reflowable.
Why convert a PDF to MOBI?
MOBI is the old Mobipocket and early-Kindle e-book format, so people convert to read a PDF on older Kindle devices or apps that still accept MOBI.
Where can I read a MOBI?
MOBI opens in Calibre and FBReader and on older Kindles. Note that Amazon retired MOBI from Send to Kindle in 2022, so EPUB is now the preferred format for Kindle.
What about scanned PDFs?
A scanned, image-only PDF has no text layer and will not reflow into real text without OCR first. Complex formatting and some images may also be lost in the reflow.
