EPUB vs MOBI
EPUB · Electronic Publication
EPUB is the open, reflowable ebook standard read by Apple Books, Kobo, Google Play Books and most e-readers. Text adapts to any screen — the format to pick for everything except Kindle.
MOBI · Mobipocket
MOBI is the legacy Kindle ebook format. Newer Kindles prefer EPUB/AZW3, but MOBI still side-loads onto older devices and reading apps.
EPUB to MOBI — frequently asked questions
Will the chapters and table of contents survive?
Yes — structure, TOC and basic styling carry across. Reflowable EPUBs convert best; fixed-layout or heavily designed books may shift slightly.
Does this work on DRM-protected books?
No. Conversion only works on DRM-free files you have the right to convert — it can't and won't strip store DRM.
How do I convert EPUB to MOBI?
Drop your EPUB file (or several) into the converter, confirm MOBI is selected as the output, click convert, then download the MOBI file. The whole thing takes a few seconds.
Is this EPUB to MOBI converter free?
Yes — it's completely free with no watermark and no sign-up required.
Is it safe to convert EPUB to MOBI here?
