PDF → EPUB
Converting a novel from PDF (.pdf) to EPUB (.epub) is a routine step in practice — EPUB is the universal e-book format: it adapts to any screen and font size, and carries a table of contents. Going from PDF to EPUB does raise extra questions worth thinking about: you lose exact pagination and element positions. Below we explain in detail how PDF becomes EPUB and what to watch out for, and the page ends with a converter that does the job right in your browser — nothing is uploaded, the file never leaves your machine.
What is PDF?
PDF records where things are drawn on a page rather than a paragraph structure, and that is what lets it freeze a layout: fonts, columns and figure positions look identical on every device and print exactly as they appear on screen. The trade-off is that it cannot reflow and the reader cannot change the font size, so long text means zooming and panning on a small screen. It suits work whose layout must be preserved — papers, contracts, scans, print-ready files — and documents that need to be archived unchanged. Read the PDF format guide

What is EPUB?
EPUB is the most portable e-book format outside the Kindle ecosystem. It is really a ZIP archive holding XHTML content, CSS, images and a manifest that fixes the reading order. Because content and presentation are stored separately, the same file re-lays-out itself for a phone, a tablet or a desktop, and the reader can change the font size at any time. The table of contents, cover, title and author all have standard places, so library software recognises and sorts the book correctly. For text-heavy fiction, EPUB is usually the safest format to distribute and to keep long term. Read the EPUB format guide

How to convert PDF to EPUB
Line breaks in PDF are mostly visual, not paragraph ends: one paragraph may arrive as five separate text blocks, each with its own hard return. Merging them back requires heuristics based on line width and sentence endings. A scanned PDF has no text layer at all, so extraction returns nothing until you run OCR.
EPUB is not just a ZIP: it must contain mimetype (as the first, uncompressed entry), META-INF/container.xml, the content OPF and a nav document. Miss one and readers report a corrupt file, so prefer a mature converter over hand-building the archive.
Layout must be rebuilt: the paragraph, column and figure positions in the source were arranged for a fixed page and mean nothing once the target reflows. The converter can only re-stitch a text stream, so paragraphs may merge wrongly, columns may interleave and figures may land mid-sentence. Read the first few chapters afterwards, watching dialogue breaks and figure placement.
The source is one full-page image per page while the target reflows: each image is inserted in sequence, and with no text layer you end up with an image stream. The result is usually huge and unsearchable — a worse reading experience than the original.
The source has no chapter concept (comics and PDFs are page-based) while the target expects navigation. The converter can only split mechanically by page or fixed length, producing a semantically empty TOC. Ignore it if you do not need navigation, but do not expect real chapters to appear.

These settings are written into the EPUB. The font size is relative, so readers can still adjust it themselves.
The conversion runs entirely in your browser — your file is never uploaded.
