Frequently Asked Questions

1 Does the converted MOBI display cleanly on Kindle?
Yes. MOBI is a classic standard format specifically built for older Kindle readers and Mobipocket applications, ensuring pixel-perfect reflow support.
2 What happens to PDF tables or charts during MOBI conversion?
Because MOBI structures are reflowable, complex multi-column grid tables are styled as responsive blocks. Highly styled layouts may need manual sizing checks.
3 Can I set my own custom book cover image?
Yes. The settings panel allows you to upload any `.jpg` or `.png` graphic to package as the official front cover art block inside the MOBI metadata schema.
4 Does the converter support scanned PDF document books?
To extract text from graphic page scans, you will first need to process the PDF through an OCR scanner module. This converts image coordinates into selectable characters.
5 Are my private novels, drafts, or ebooks sent to remote servers?
No. All document parsing, cover rendering, and MOBI packaging occur inside your local browser memory space. We never store or transmit your book files or user metrics.
