does epub to pdf keep original formatting

An EPUB file bundles the book's text as HTML alongside separate stylesheets, embedded fonts, and images that a dedicated e-reader app uses to render each page's specific look. This converter reads out the plain text content from the HTML — headings, paragraphs, lists — and discards the styling, font, and image data entirely, since those are separate files within the EPUB package that a text-extraction approach doesn't touch.

The output PDF uses a single standard font applied uniformly throughout the document, regardless of what fonts the original book used. There's no per-chapter styling, no pull quotes rendered specially, no embedded cover art or illustrations — just the readable text, formatted simply and consistently.

This is a deliberate trade-off, not a missing feature waiting to be added: preserving an EPUB's exact visual rendering would require essentially re-implementing an e-reader's layout engine, which is a much larger undertaking than extracting and reformatting text. For the common goal of getting an ebook's content into a searchable, printable, annotatable PDF, text extraction is the practical and sufficient approach.

If visual fidelity to the original book matters more than having the text in PDF form — for example, preserving illustrations in an illustrated book, or exact typography for a design-heavy publication — this tool's plain-text approach won't deliver that, and a different, more specialized conversion path would be needed.
