How do I convert a PDF to MOBI?

Upload your PDF file, select MOBI as the output format, and click Convert. Once the conversion process finishes, download the MOBI file and transfer it to your e-reader via USB or email. Your PDF's text is reflowed and images are embedded to match Kindle and other e-reader specs.

Why convert from PDF to MOBI?

MOBI is the native format for older Kindle devices and many e-reader apps. Unlike PDF's fixed page layout, MOBI reflows text to fit any screen size, making reading more comfortable. MOBI files are often smaller than PDFs because text is dynamic and images are compressed for e-ink displays.

How does the conversion handle text, images, and layout?

During conversion, vector text is converted into editable reflowable text, while embedded images are re-encoded and compressed to the device's optimal resolution. Complex layouts, such as multi-column pages or fixed backgrounds, may not translate perfectly; they are simplified for linear reading. Page numbers and fixed positioning are not preserved, but bookmarks and metadata are carried over where possible.
