Converting a PDF to EPUB is the best way to optimize documents for eReaders, but the process has key tradeoffs and pitfalls to understand before you start.
Quick Answer: Why Convert PDF to EPUB for eReaders?
EPUB is a reflowable ebook format, meaning text adjusts to fit your device’s screen and your preferred font size. PDF files, by contrast, are fixed-layout: they preserve the original page design, which often results in tiny, hard-to-read text on eReaders. Converting PDF to EPUB makes books and documents much more readable on Kindles, Kobos, and other eReaders, but some elements—like complex layouts, columns, or embedded fonts—may not convert perfectly.

Practical Steps to Convert PDF to EPUB
1. Assess Your PDF
- Simple PDFs: Mostly text, single column, basic images. These convert cleanly to EPUB.
- Complex PDFs: Multiple columns, tables, footnotes, graphics, or scanned images. Expect mixed results—manual cleanup may be needed.
- Scanned PDFs: Basically images, not text. Require Optical Character Recognition (OCR) to extract text for EPUB.
2. Choose a Conversion Method
- Online converter: Easiest for most users. Upload your PDF, download the EPUB. Works best for text-based PDFs.
- Desktop software: Tools like Calibre offer more control and batch features, but can be intimidating. Good for power users and large libraries.
- Manual editing: For perfect results or highly formatted documents, you may need to export to HTML first, clean up formatting, then convert to EPUB.
3. Use an Online Converter (Recommended for Most)
FileConversion.co provides a straightforward PDF to EPUB conversion tool. Steps:
- Go to FileConversion.co PDF to EPUB.
- Upload your PDF file.
- Download the resulting EPUB.
4. Check the EPUB on Your Device
- Transfer the EPUB to your eReader (via USB, email, or cloud sync service).
- Open it and check for missing text, broken formatting, or misplaced images.
- Adjust font size and style to test reflow.
5. Fix Conversion Issues (If Needed)
- For minor issues, try converting again with different settings.
- For major formatting problems, consider using a desktop tool like Calibre or Sigil for manual editing.
PDF vs. EPUB: Format Comparison for eReaders
| Feature | EPUB | |
|---|---|---|
| Layout | Fixed (original page preserved) | Reflowable (adapts to screen) |
| Font Size Control | None on most eReaders | Full user control |
| Images | Embedded, may not scale well | Supported, but may reposition |
| Tables/Columns | Preserved as in original | Often lost or require cleanup |
| Annotations/Notes | Supported in some readers | Supported in most eReaders |
| DRM Support | Sometimes (Adobe DRM) | Often (Adobe, Apple, Kobo, etc.) |
| Accessibility | Often poor, especially for scans | Generally better, with limitations |
| File Size | Often larger | Generally smaller |
Bottom line: Use EPUB if you want a comfortable, resizable reading experience. Use PDF only if you must preserve the exact original layout.
Common Problems, Limitations, and Edge Cases
Layout and Formatting Loss
- Multi-column layouts in PDFs can confuse converters, resulting in jumbled text order in EPUB.
- Headers, footers, and page numbers may be inserted into the main text.
- Tables may not convert cleanly, often turning into plain text or losing structure.
- Fonts and special symbols may be changed or dropped, especially if not embedded in the PDF.
Images
- Image placement may shift in EPUB, especially for images anchored to specific spots in the PDF.
- Background images, watermarks, or decorative elements may not appear at all.
Scanned PDFs
- Scanned documents are images, not text. EPUB conversion requires OCR, which can introduce errors or miss formatting altogether.
Metadata Loss
- Document metadata (title, author, etc.) might not transfer automatically. You may need to add or edit this in the EPUB afterward.
eReader Compatibility
- Kindle: Does not natively support standard EPUB files until recent models. You may need to convert EPUB to AZW3 or MOBI, or use Send-to-Kindle (which now supports EPUB).
- Kobo, Nook, others: Full EPUB support, but some advanced features (like embedded fonts or interactive content) may not work as expected.

Frequently Asked Questions
Will hyperlinks and bookmarks in my PDF work in the EPUB?
Some online converters preserve hyperlinks, but bookmarks and internal navigation rarely survive. Manual editing may be required to restore them.
Why does my EPUB look strange on my eReader?
PDF’s fixed layout doesn’t always translate well to reflowable EPUB. This is especially true for multi-column layouts and documents with many images, tables, or footnotes.
My PDF is a scan—can I still convert it?
Yes, but you need OCR (Optical Character Recognition) first. Use FileConversion.co PDF to TXT to extract the text, then convert that text to EPUB. Accuracy depends on scan quality.
What about DRM-protected PDFs?
DRM (Digital Rights Management) prevents conversion without removing the protection, which is not supported by most legal tools.
How do I transfer the EPUB to my eReader?
For Kindle, email the EPUB to your Kindle address. For Kobo, Nook, and others, connect via USB and copy the file to the "Books" or "Documents" folder.

- Use FileConversion.co PDF to EPUB for fast, easy conversion of text-based PDFs.
- For scans, run OCR first with FileConversion.co PDF to TXT.
- Check your EPUB on your eReader before deleting the PDF; some cleanup may be needed.
