When a PDF won't sit still on a small screen

Four PDFs. Four readable ebooks.

For the times a PDF is unreadable on the device you actually have.

"500 pages, pinch-zooming on a phone."

A grad student in Lisbon has a 500-page reader trapped in a fixed PDF. On the train she's pinch-zooming every line. Converts to MOBI — the text reflows, the font bumps up, she reads hands-free.

"My Kindle won't open this report."

A founder in Berlin sends a PDF report to his Kindle. It lands as tiny fixed pages he can't read. Converts to MOBI first — now it reflows, and he gets through it on the commute.

"The whole syllabus on one e-reader."

Reviews from people who actually read the ebook.

"It actually reflows."

I read research on my Kindle. This is the only converter where the text truly reflows instead of staying a tiny fixed page. Chapters even show up in the table of contents.

"My whole reading list, reflowed."

I had 30 report PDFs to get onto my Kobo. Converted them all in 10 minutes — every one reflows and remembers my place. They used to be unreadable on that screen.

"Even kept the images and TOC."

I converted an illustrated PDF. The images, the chapter breaks, even the table of contents came through. Opened it in Apple Books and adjusted the font instantly.

Questions about PDF to MOBI.

Don't see your question? Our team replies within 24 hours.

Yes. We don't keep fixed PDF pages — we extract the text and rebuild it as a reflowable MOBI. Change the font, the size or the orientation and the text re-wraps to fit your Kindle screen.
Yes. Headings become a clickable table of contents and inline images are embedded in the MOBI. Because MOBI reflows, fixed multi-column or heavily designed pages (magazines, infographics) become one readable flow rather than an exact replica.
Yes. Our AI-powered OCR turns scanned images into real ebook text in 100+ languages. Accuracy averages 99.4% on English, 98%+ on most European languages.
Your first conversion is free, no signup needed. Paid plans cover unlimited conversions, batch processing and team features — but the essentials stay free.
Files are encrypted with 256-bit SSL during upload and at rest, auto-deleted 1 hour after you finish. SOC 2 Type II certified, GDPR compliant.
