Why convert MOBI to PDF?
MOBI is an old Kindle format that most other devices cannot open. A PDF opens on any computer or phone and can be printed, so converting MOBI to PDF makes the book readable everywhere.
When to keep the MOBI
Keep the MOBI if you read the book on an older Kindle, which handles MOBI better than PDF pages.
Tips for the best result
- Text, chapters and images are kept.
- The PDF has fixed pages; on a phone, EPUB is often nicer to read.
- Books bought from Kindle, Kobo or Google Play are usually DRM-protected and cannot be converted. DRM-free books, such as those from Project Gutenberg or many independent authors, work.
Common problems and fixes
- The file will not convert.
- MOBI files from the Kindle store are usually DRM-protected and cannot be converted.
- Text is small on my phone.
- PDF pages do not reflow. Use MOBI to EPUB for a format that adapts to the screen.
PDF – Portable Document Format
PDF is the standard format for documents that must look the same on every device. It preserves layout, fonts and images, but is difficult to edit.

Frequently asked questions
Can I print a MOBI book?
Convert it to PDF first, then print the PDF.
Is MOBI still used?
Amazon has moved to newer formats and Send to Kindle no longer accepts MOBI, so converting old MOBI files to PDF or EPUB is a good idea.
How do I convert MOBI to PDF?
Click Select File or drop your MOBI file onto the upload box. The converted PDF appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
