Frequently Asked Questions

Why convert PDF to MOBI for Kindle?▼
PDFs on Kindle are displayed as fixed-layout images — text is tiny and requires constant zooming. MOBI reflows to fill the screen at any font size, making reading far more comfortable.
Are images from the PDF included in the MOBI?▼
Yes. Images embedded in the PDF are included in the MOBI output.
Does the conversion work for all PDFs?▼
Best results with text-based PDFs (articles, books, reports). Scanned PDFs (image-only), heavily designed documents, and scientific papers with complex math may not convert well.
Should I use this for new Kindle devices?▼
For Kindle devices from 2022 onwards, you can send the PDF directly or use EPUB format, which is now natively supported. MOBI is still useful for older Kindles.
Is the conversion done in the browser?▼
Yes. Text extraction from PDF and MOBI packaging both happen locally. Your file is never uploaded to any server.
