TransformaHow to Convert ePub to PDF on iPhone
ePub is a reflowable ebook format that adapts to different screen sizes, but sometimes you need a fixed-layout PDF for printing, sharing, or reading on devices that don't support ePub. Transforma converts ePub files to PDF entirely on your iPhone, preserving chapter structure and embedded images. The conversion uses Apple's rendering pipeline to produce clean, paginated output from your ebook content.
Quick Answer
Open your ePub file in Transforma, tap PDF as the output format, and convert. Chapter structure and images are preserved in the PDF, and the entire conversion happens on your iPhone with no uploads.
Why You Might Need This
- PDF is universally supported while ePub requires a dedicated ebook reader, making PDF better for sharing with anyone.
- Printing ebook content requires a fixed-layout format like PDF — ePub's reflowable text doesn't translate well to paper.
- Some professional and academic contexts require PDF submissions, even when original content was authored in ePub.
- PDF preserves the exact visual appearance across all devices, unlike ePub which renders differently on each reader.
Step by Step
Open Transforma and select your ePub file
Launch Transforma and browse to your ePub file. You can import from the Files app, iCloud Drive, or any connected storage provider.
Choose PDF as the output format
Tap PDF from the available output formats. Transforma will extract the chapter content and render it using Apple's rendering pipeline to produce a formatted PDF.
Review the converted PDF
Preview the output to verify that chapter structure, headings, and embedded images have been preserved correctly. Note that formatting is approximate since ePub's reflowable nature means the original had no fixed layout.
Save or print the PDF
Save the PDF to your device or share it directly. You can also use iOS's built-in print dialog to send the converted PDF straight to a printer.
Tips for Best Results
- Chapter structure from the ePub is preserved and mapped to PDF sections, keeping your ebook organized.
- Fixed layout in PDF means text won't reflow on different screens — what you see is exactly what every reader will see.
- The conversion is ideal for printing excerpts or full ebooks, since PDF handles page breaks and margins properly.
- Formatting is approximate because ePub is inherently flexible — the PDF captures one possible rendering of the reflowable content.
- Embedded images from the ePub are included in the PDF at their original resolution.
Frequently Asked Questions
Is chapter structure preserved in the PDF?
Yes. Chapters from the ePub are mapped to sections in the PDF, maintaining the organizational structure of the original ebook. Headings and hierarchical formatting carry over so you can navigate the PDF by chapter.
Can I select specific chapters to convert?
You can extract specific chapters using Transforma's chapter extraction capability. This lets you convert individual sections of an ePub to PDF without processing the entire book.
Will images be included in the PDF?
Yes. Embedded images from the ePub are preserved in the PDF output at their original resolution. Cover images, illustrations, and inline graphics all carry over to the converted file.
Can I convert the PDF back to ePub?
No, PDF to ePub is not supported. ePub requires structured semantic markup with reflowable content, which cannot be reliably reconstructed from a PDF's fixed layout. Keep your original ePub file if you need it in that format.
