❓ Frequently Asked Questions

What is the difference between EPUB and KePub on Kobo?

Standard EPUBs on Kobo are rendered by the older RMSDK engine, which is slower and lacks stats. KePub (Kobo EPUB) uses Kobo's proprietary ACCESS engine, providing instant page turns, pop-up footnote previews, chapter reading time graphs, and smooth image zooming.

Can I download KePub files directly on my Kobo without a cable?

Yes! On your Kobo e-reader (Clara, Libra, Sage, Elipsa), open More → Beta Features → Web Browser, navigate to pureepub.com/pdf-to-kepub, and convert your file. Tap download, and the book will automatically be added to your Kobo library.

Why is PureEPUB better than Calibre or Kepubify for PDFs?

Tools like Kepubify only convert EPUB to KePub, not PDFs. Calibre converts PDFs mechanically, leaving broken mid-sentence line breaks and hyphenated words. PureEPUB uses a specialized line-healing engine that detects sentence flow and OCR errors before generating the KePub.

Are my uploaded PDF books stored on your server?

Never. PureEPUB operates with a strict Zero Data Retention policy. Files are processed entirely in ephemeral memory and immediately destroyed after conversion.
