PDF to EPUB is the conversion most likely to disappoint: the images vanish and the text arrives as one long, unbroken block. The result depends almost entirely on what kind of PDF you started with. This guide shows how to keep images and get a readable EPUB.
Scanned PDF vs native PDF (this changes everything)
There are two very different PDFs:
- A native PDF was exported from a word processor or layout tool. Under the hood it contains real, selectable text.
- A scanned PDF is just a sequence of page images — a photo of every page. There is no text to extract, only pictures.
If your "PDF" is a scan, no converter can magically recover a clean EPUB. You first need OCR (optical character recognition) to turn those pictures into text.
Why images disappear
When a tool converts a native PDF, it typically pulls the text layer out and rebuilds an EPUB around it. If the converter is set to "text only," it discards the original page images, diagrams, and photos. That is why your illustrated PDF comes out as bare paragraphs.
The fix is to use a converter that carries the embedded images through. BookConv does this for native PDFs: /convert/pdf-to-epub.
Scanned PDFs need OCR first
For a scan, run OCR (for example in Acrobat, or a free OCR tool) so the file gains a real text layer. After that, convert to EPUB and the text will reflow properly instead of being trapped inside page-image snapshots.
If the source is a comic or highly visual document, an EPUB will never match the fixed layout — keep it as PDF, or convert the pages to images with /convert/cbr-to-pdf style tooling.
Convert with BookConv or Calibre
BookConv (online, no install): upload a native PDF, choose EPUB, and embedded images are preserved while text becomes reflowable. Best for most users.
Calibre (desktop): open the PDF, pick EPUB as output. Calibre is decent at native PDFs but, like every tool, it cannot invent text from a scan. For a deeper look at the trade-offs, see /blog/pdf-to-epub-guide — including when you should not convert.
Set expectations: layout will change
EPUB is reflowable, so a precisely laid-out PDF (multiple columns, side notes, fixed caption positions) will not survive conversion unchanged. Accept that the EPUB will be a clean reading version, not a pixel copy. If you need the exact layout, keep the PDF.
