Why convert PDF to MOBI
Emailing a PDF to a Kindle keeps its page geometry, so an A4 page arrives squeezed onto a six-inch screen and the type ends up unreadably small. The device cannot rewrap a PDF, only shrink it.
Converting to MOBI extracts the text and reflows it to the device width, so font size finally does something. Figures come across as images; multi-column tables are the weak spot of any PDF extraction and can flatten into a single column.
PDF vs MOBI
| MOBI | ||
|---|---|---|
| Reflow | Fixed page, lines never move | Text rewraps on Kindle hardware |
| Font size | Zoom only, then pan sideways | Kindle sizes, limited styling |
| Images | Pinned to their page position | Simplified and often downscaled |
| Best for | Forms, invoices, print layouts | Older Kindles and legacy apps |
PDF to MOBI questions
Why not just email the PDF to my Kindle?
A PDF on a small e-ink screen keeps its page geometry, so the type stays tiny. Converting to MOBI reflows the text to the device width.
Will tables and figures look right?
Figures are kept as images. Multi-column tables are the weak spot of any PDF extraction and can come out flattened into a single column.
Does this work on a scanned book?
Only if the scan already carries an OCR text layer. Without one there is no text to reflow.
