Convert PDF to EPUB Online Free — PDF to eBook Converter

Turn any text-based PDF into a beautifully formatted ebook. Read on Kindle, Kobo, Apple Books, and any e-reader.

Why Convert PDF to EPUB?

PDFs are designed for fixed-page printing — they don't adapt to different screen sizes. Ebook formats like EPUB use reflowable text, meaning content automatically adjusts to any screen size or font setting. Converting your PDF to EPUB makes it comfortable to read on a phone, tablet, or dedicated e-reader without zooming and scrolling.

Our converter uses Calibre — the industry-standard open-source ebook management tool — to ensure high-quality, standards-compliant output every time.

Frequently Asked Questions

Can I convert a scanned PDF to EPUB?

No — scanned PDFs contain only images with no extractable text. To convert a scanned PDF, first run it through our OCR PDF tool to create a text-based PDF, then convert it to ebook format.

Which ebook format should I choose?

EPUB is the most universal format and works on Kobo, Apple Books, Google Play Books, and most e-readers. Choose MOBI for older Kindle devices or AZW3 for newer Kindle devices with the richest formatting support.

Will my PDF formatting be preserved?

Ebooks use reflowable text rather than fixed page layouts, so the content will reflow to fit any screen. Simple single-column PDFs convert very well. Complex multi-column or heavily designed layouts may reflow differently.

Is there a file size limit?

You can convert PDFs up to 100 MB for free. Most documents and books are well within this limit.
