EPUB and PDF solve different distribution problems, so neither format is universally better for self-publishing. EPUB is the better fit for e-reader and digital book distribution because it uses reflowable layout that adapts to any screen. PDF is the better fit for review copies, print-style handoff, and anywhere fixed-layout rendering matters. In Gixo Folio, that format choice happens after the manuscript is finalized, not before.
A format list is the starting point. Inspect print and ebook controls, freeze the manuscript and settings, then review the actual artifact that will leave the workspace.
Set standard or custom trim, mirrored margins, bleed and page headers. Inspect measured figure warnings; the paperback wrap uses the rendered interior's page count.
PDF is RGB, not PDF/X. EPUB 3 is reflowable; fixed-layout spreads and automatic index/bibliography generation are not provided.
Save a frozen edition, inspect its PDF or ebook artifact, add proof notes and corrections, and reproof changed files. Editorial clearance stays with that edition.
Approval is your recorded decision for one artifact. Later manuscript or layout changes need a new proof.
Choose the reviewed file, confirm provenance and destination requirements, then download the author handoff package and upload it yourself.
Folio does not issue ISBNs, publish to retailers or certify acceptance. Translation and audio are separate workflows.
Start blank, import and manually edit your own book. Its downloads and proofs do not need an active Folio subscription. New AI planning, drafting and editorial assistance need eligible access; translation and narration use separate edition conditions. Existing book view, comment and edit permissions apply.

Use the persistent book workspace when the outcome is a real guide, authority book, training manual, client asset, or exportable edition.
If your manuscript is already finished and you only need specialist formatting or a dedicated fiction system, a focused tool may be the simpler choice.
Treat the format as a distribution decision, not a drafting decision.
Ask about the destination, not your personal preference.
Neither format is universally better; each is better for a different job.
| Decision area | EPUB | |
|---|---|---|
| Best for | Digital book distribution and e-readers | Review copies, fixed-layout sharing, print-style handoff |
| Layout behavior | Reflowable | Fixed |
| When to choose | The destination expects digital reading behavior | The destination expects stable pages or print-like review |
| What matters most | Device adaptability | Layout consistency |
| How Gixo handles it | Available in the same final export flow after review | Available in the same final export flow after review |
A lot of buyers think the format is the main decision, but the harder problem is usually whether the manuscript is finalized. Once the book has been revised and reviewed in the workspace, the EPUB-versus-PDF decision becomes much clearer.
That is why Gixo Folio keeps the export step at the end of the workflow.
Gixo Folio keeps EPUB and PDF inside the same final export flow, so the decision happens after the manuscript is finalized rather than in the middle of drafting. That makes the output choice calmer and more practical.
Ordinary book export supports several file formats. International translation and audiobook services have separate edition downloads and access conditions.
