About formats

MOBI

MOBI is an e-book format originally developed by Mobipocket and later acquired by Amazon. MOBI files are based on the Open eBook standard and support DRM protection, bookmarks, annotations, and reflowable text. MOBI was the primary format for Kindle devices until being superseded by AZW3/KFX. MOBI files can still be read by Kindle apps, Calibre, and many third-party e-readers.

Which devices and platforms can I use to convert MOBI to PDF?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my MOBI files uploaded to a server?
No. Files never leave your device. The entire MOBI → PDF conversion runs locally in your browser, so your data stays private.
Can I convert multiple MOBI files at once?
Yes — batch conversion is supported. Add as many MOBI files as you like and convert them to PDF in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting MOBI to PDF lose quality?
No. PDF is a lossless format (or used in a lossless mode here), so the original data from your MOBI file is preserved bit-for-bit in the converted result.
Does PDF support transparency from MOBI?
Yes. PDF supports an alpha channel, so any transparent regions of your MOBI file will be preserved as transparent in the converted file.
How will the file size change after converting MOBI to PDF?
Both formats use comparable compression, so the PDF output will be similar in size to your MOBI file — typically within 10–20% of each other.
