How do I convert a DOC file to MOBI?

Upload your DOC file to the converter, select MOBI as the output format, and click 'Convert'. After processing, download the MOBI file and transfer it to your e-reader via USB or email. The conversion preserves document structure, so headings, page breaks, and images are adjusted for a smooth reading experience.

Why should I convert DOC to MOBI instead of keeping it as DOC?

MOBI is optimized for e-readers like Kindle, while DOC is a word-processing format meant for editing and printing. Converting to MOBI makes your document readable on e-ink screens, reduces file size due to reflowable text, and enables ebook features like chapter navigation and bookmarks.

What happens to images and formatting during DOC to MOBI conversion?

Images are embedded as JPEG or PNG and scaled to fit your e-reader's screen. Headings and paragraphs are mapped to MOBI's semantic HTML structure, but complex page layouts, custom fonts, and fixed spacing are lost because MOBI uses reflowable flow. Footnotes may be converted to endnotes depending on your device.
