Accepts EPUB, MOBI, AZW3, FB2 · up to 500.0 MB per file · up to 20 files at once
You can also paste a file with Ctrl/Cmd+V, or from the clipboard menu.
Ebook to PDF runs Calibre `ebook-convert` on `.epub`, `.mobi`, `.azw3`, or `.fb2` and writes a PDF. There are no paper-size, font, or margin fields on this page.
Conversion quality is Calibre's default PDF profile for that input. DRM-encumbered Kindle files fail. Fixed-layout EPUBs and comic EPUBs may paginate oddly.
This is not OCR. A scanned ebook that is already images stays images. PDFs and office files belong on other tools.
The output is a PDF named from the source base name. Encrypted inputs that Calibre cannot open are errors, not an unlock tool.
