Our online converter supports these popular eBook formats:

• EPUB (the most common open eBook format)

Converting an eBook to PDF gives you a stable file you can read, share, and print anywhere.

• Universal compatibility: PDFs open on phones, tablets, laptops, and e-readers.

• Preserved formatting: Fonts, images, and layout stay consistent on every device.

• Easy sharing: Send PDFs by email or cloud storage with no format issues.

• Print-ready: Pages stay aligned, so chapters and images print cleanly.

• Annotation support: Add notes, highlights, and bookmarks across all PDF readers.

While online conversion is the quickest method, you have other options depending on your needs.

1. Save as PDF from Reading Apps

Many eBook reading apps offer a “Save as PDF” or “Export as PDF” option:

1. Open your eBook in the reading app

2. Look for export or sharing options in the menu

3. Select “Save as PDF” if available

This works best for EPUB and MOBI files already optimized for reading.

2. Print to PDF Option

Due to Digital Rights Management (DRM) protection, not all eBooks are printable. But if your eBook is in a format you can open in a web browser or document viewer, you may be able to use the “Print” option to save this file as a PDF. 

Here's how:

1. Open your eBook in a compatible application.

2. Access the print dialog by pressing Ctrl+P (on Windows) or Command+P (on Mac).

3. Look for a printer option labeled “Print to PDF” or “Save as PDF.”

4. Choose that option, select your destination folder, and save the file.

This method works only with files that do not contain DRM protection.

3. Desktop Software Solutions

Calibre is a free, open-source eBook management program that lets users convert eBooks to various formats, including PDF.

Here's how you can use Calibre to convert eBook to PDF format:

1. Download and install Calibre.

2. Open Calibre and add an eBook by clicking on the “Add books” button.

3. Select your eBook and click on the “Convert books” button.

4. In the conversion window, select “PDF” as the output format and adjust any settings as needed.

5. Click “OK” to start the conversion process. Once completed, the PDF file will be saved in your Calibre library.

Desktop software works well for bulk conversions or when you need advanced formatting control, but online tools are faster for individual files.

Smallpdf handles most conversions smoothly, but a few issues may appear depending on the source file.

1. The eBook does not upload

Check that the file format is EPUB, MOBI, AZW, AZW3, FB2, or DOCX. If the file size is unusually large, try compressing it first.

2. The PDF exports with missing images

Some eBooks embed images with non-standard encoding. In this case, try re-exporting from a reading app or use the desktop method.

3. The file cannot be converted

This usually indicates DRM protection. DRM blocks copying and conversion, and the file must remain inside its original reading environment.

You can convert eBooks you own for personal use. Converting or distributing copyrighted eBooks for others violates copyright laws. DRM-protected files cannot be converted because the protection prevents copying or reformatting the text.

Smallpdf secures every upload with 256-bit SSL encryption. All files delete automatically after one hour, and we never access your documents. Your conversion stays private and fully protected under GDPR-compliant data handling.

Once your eBook becomes a PDF, you can refine it with our built-in features:

• Compress: Reduce file size without losing quality.

• Merge: Combine multiple books into one file.

• Split: Extract specific chapters or sections.

• Edit: Add notes and highlights for better reading.

• Protect: Add password security to sensitive documents.

These features help you prepare, store, and personalize your digital library in one place.

Smallpdf turns your eBooks into universal PDFs that read cleanly on any device. Convert your files online, preserve the layout, and continue editing with built-in features.
