COMMON QUESTIONS

Frequently Asked Questions

Ebook layouts & Kindle file rules explained
? How does the PDF to MOBI converter work?
It reads the vector character maps from the PDF stream, structures standard XHTML pages, and packages them into the MOBI container.
? Are my private PDF documents uploaded to online databases?
No. All decompression, text analysis, coordinate mapping, and eBook compiling are executed locally in your browser memory.
? What is a MOBI file?
MOBI is a popular eBook format originally designed for Mobipocket readers and commonly supported by Kindle and other e-reading devices.
? Will pictures embedded in the PDF be preserved?
Yes. Embedded pictures are extracted, converted into WebP or JPEG format, and embedded inline with the surrounding text sections.
? How does the converter handle columns?
It scans boundary layout guides to read and wrap double-column text sequentially rather than horizontally across dividers.
? Can I load the output MOBI onto my Kindle?
Yes! You can transfer the converted MOBI file directly to your Kindle device or send it via email for immediate reading.
