Is this EPUB to PDF converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple EPUB files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

Will my document formatting survive conversion?

Standard formatting — text, headings, bold/italic, tables, and inline images — transfers reliably. Complex layouts with floating objects, custom fonts, or SmartArt may simplify. Always give the output a quick review before sharing.

Can I convert a password-protected document?

No — encrypted files can't be read without decryption, and we never ask for passwords. Remove the password protection first, then convert.

Will the PDF preserve the ebook's chapters and table of contents?

Yes. Chapter structure, headings, and the table of contents are preserved in the output. Standard text-heavy ebooks convert cleanly. Fixed-layout EPUBs — used for children's books or heavily designed publications — may not convert as faithfully.

Can I convert DRM-protected ebooks?

No. Ebooks purchased from Amazon Kindle, Apple Books, or Google Play Books are DRM-encrypted and can't be converted. Only DRM-free EPUBs — from Project Gutenberg, Standard Ebooks, or DRM-free stores — will work.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert EPUB to PDF?

EPUB is the right format for reading — text reflows, fonts adjust, and it's designed for screens of all sizes. PDF is the right format for everything else: printing, sharing with others, reading on devices without an ebook reader, and filing away in a folder that anyone can open.

Most people arrive at epub-to-pdf because they downloaded an ebook they want to print, share with a colleague who doesn't have a Kindle or ebook app, or read in their preferred PDF viewer. The problem is that EPUB requires a dedicated reader — Apple Books, Kindle app, Kobo, Calibre — and if you don't have one installed, you're stuck with a file you can't open.

A PDF opens in every browser, every phone, every OS, and every printer driver. It's the lowest-friction sharing format. The converted PDF preserves the chapter structure, headings, and text of the EPUB. Complex ebooks with heavy custom formatting (fixed-layout EPUBs, those with lots of custom CSS or embedded media) may not convert perfectly, but standard text-heavy ebooks come through cleanly.

Common reasons to convert EPUB to PDF:

›Printing an ebook for physical reading or annotation
›Sharing a book with someone who doesn't have an ebook reader installed
›Archiving a book in a format that doesn't require specific software to open
›Reading on a device or in an app that handles PDF but not EPUB

Quality & file size: EPUB to PDF

Typical file sizes: EPUB 300 KB–2 MB → PDF 100–500 KB.

Both EPUB and PDF use lossless compression, so no quality is lost in conversion. The output PDF file will be visually identical to the EPUB source.

Color depth: EPUB supports standard color, PDF supports standard color.

Transparency: EPUB does not support transparency. PDF does not support transparency — transparent areas become solid white.
