MOBI vs PDF — what changes
A Palm-era format Amazon retired in 2022. Text reflows, styling is minimal, and fewer and fewer apps open it.
Every page frozen at the size you choose, readable on anything with a screen, printable forever.
Questions
Would EPUB be a better target than PDF? +
If you want to keep reading on an e-reader, yes — EPUB stays reflowable, and the MOBI to EPUB tool does that conversion. Choose PDF when you want printing, annotation, or a file that renders identically everywhere.
Does this work with DRM-protected books? +
No. Files with DRM can’t be opened by any converter. This tool works with DRM-free files — like the ones you export from your own writing tools or buy from DRM-free stores.
Is there a file size limit? +
There is no size cap — nothing is uploaded, so no server quota applies. The real ceiling is your device’s memory, because the whole file is held in RAM while it converts: a novel is trivial anywhere, a very large illustrated book can be slow or run out of memory on an older phone. If one struggles, run it through the EPUB Compressor first — it usually shrinks image-heavy books by half.
Are my files private? +
This tool runs entirely inside your browser — your file is never uploaded anywhere. It stays on your device, and closing the tab is all it takes to remove it.
Is it really free? +
Yes. Every tool, no size cap, no account. There is no paid tier and nothing is held back.
