Why convert PDF to EPUB

A PDF is a picture of a printed page: the lines break where the designer decided, at a size chosen for A4 paper. On a phone that means zooming in, dragging sideways and losing your place halfway through every paragraph. An EPUB carries the same words without the fixed page, so your reader can lay them out for the screen in front of you.

Once the book reflows you get the things that make long reading comfortable: a font size you choose, working night mode, highlights that stay attached to the sentence, and a table of contents you can actually jump around in. It is the difference between tolerating a document and reading a book.

PDF to EPUB questions

Will the layout survive the conversion?

Body text, headings and the reading order carry over, and images travel with the book. A PDF built from a scan has no text layer to extract, so it becomes an EPUB of pictures rather than searchable words.

Why convert a PDF to EPUB at all?

A PDF page is a frozen sheet of paper. An EPUB reflows to the width of a phone, which is why reading apps give you font size, spacing and dark mode on EPUB and not on PDF.

How large a PDF can I send?

Up to 30 MB per file. Anything bigger is rejected in your browser before a single byte is uploaded.
