No file upload

This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.

Original stays unchanged

The converter creates a separately named output. It never writes back into the source file.

Plain-language method

How EPUB to PDF works

The browser validates the EPUB ZIP, resolves META-INF/container.xml, reads the OPF manifest and spine, removes active or embedded content, extracts visible chapter blocks, paginates them with browser fonts, and captures those pages into PDF.

01
Choose a valid source
Use a reflowable, unencrypted EPUB with a valid manifest and spine. Fixed-layout books, DRM, malformed packages, and books beyond the text or page limits are rejected.
02
Review the conversion choices
Standard quality is the safe default. High quality affects page-image resolution only; it does not recover omitted media or original publisher layout.
03
Inspect the separate result
The result follows spine order and keeps headings, paragraphs, lists, quotes, and code-like text. Publisher CSS, cover art, inline images, audio, video, scripts, fonts, links, and fixed-layout positioning are intentionally omitted.

Useful when

Practical jobs this tool handles

Create an offline reading copy of an owned reflowable ebook.
Review chapter text without uploading the book.
Produce simple pages for personal annotation.

Before converting

Check the source and destination rules

Confirm you may convert the ebook.
Check chapter order and titles.
Keep the EPUB as the accessible, reflowable source.

Know the boundary

Know what the destination format cannot keep

The PDF uses visual page captures and is not a replacement for EPUB accessibility or responsive reading. Search and text selection may be limited. Do not use this route to bypass DRM or publishing rights.

Quick answers

Questions before you convert

The conversion contract is deliberately explicit.

Does it preserve images and publisher styling?

No. This release creates a clean text-focused reading PDF.

Does it remove DRM?

No. Protected books are rejected.

Why does the page count differ from an ebook reader?

EPUB is reflowable. Page count depends on the fixed Nirmion reading-page size and available browser fonts.
