What PDF is
PDF is an open standard for fixed-layout documents. Authors and publishers decide fonts, margins and pagination at create time. Readers display that page; they do not reflow paragraphs to fit a six-inch screen the way an EPUB reader does.
That makes PDF the native home of journal articles, textbooks with complex figures, forms, comics and anything you will print with stable page numbers.
When to keep PDF as your master
- Page numbers, figures or citation layout are the product.
- The file is a scan, form, comic or sheet music.
- You annotate on a large tablet or print often.
When to prefer EPUB instead: novels, long non-fiction, and any shelf you read on phones or change fonts on. Full comparison: EPUB vs PDF.
How Fere Reader relates
Fere Reader opens PDF in the same library as EPUB and other formats. Use it when a paper or fixed layout belongs on the shelf next to your books — without forcing everything into one container.
Typography controls help most on reflowable EPUB. For PDF, expect page-faithful viewing; pinch-zoom on a phone is still a property of the format, not a bug in the app.
When conversion helps
This page is a definition, not a how-to. When you do need steps:
- PDF to EPUB — text PDFs you want to reflow
- PDF to Kindle — transfer plus when to convert first
- EPUB to PDF — freeze a page when print needs it
