PDF (Portable Document Format) is Adobe's universal document standard, designed to present text, images, and layout consistently across any device or platform. First released in 1993 and later standardized as ISO 32000, PDF supports vector graphics, embedded fonts, forms, annotations, and encryption. It has become the de facto format for document exchange, digital publishing, and archival—billions of PDFs are created daily worldwide.

PDF excels at preserving document fidelity and works universally—every operating system and browser includes native PDF support. For long-term archival or regulatory compliance, PDF/A is the appropriate variant.
EPUB (Electronic Publication) is an open ebook standard developed by the International Digital Publishing Forum (IDPF), now part of the W3C. First released in 2007 as a successor to Open eBook, EPUB has become the most widely supported ebook format. EPUB files are ZIP archives containing HTML/XHTML content, CSS styling, images, and metadata organized according to the EPUB specification.

EPUB's key feature is reflowable content—text automatically adapts to different screen sizes, making it ideal for e-readers, tablets, and phones. The format supports embedded fonts, multimedia (in EPUB 3), and accessibility features. Most e-readers except Amazon Kindle natively support EPUB.
Frequently Asked Questions
What is EPUB format?
Why convert PDF to EPUB?
Does PDF to EPUB conversion work on scanned documents?
Will my PDF's formatting be preserved?
EPUB is a reflowable format, which means complex PDF layouts (multi-column text, precise positioning, embedded forms) cannot be perfectly preserved. The converter extracts text and basic structure (headings, paragraphs, images) but the exact visual layout will differ.
Best results: Text-heavy documents like novels, reports, and articles. Less ideal: Heavily designed PDFs like magazines, brochures, or forms.
Can I convert password-protected PDFs?
No. Password-protected PDFs cannot be converted. You must remove the password protection first, or provide the password to unlock the document. Contact the document owner for an unprotected version if needed.
What devices support EPUB?
Should I convert PDFs to EPUB or MOBI for Kindle?
How is this different from PDF to DOCX conversion?

How are credits calculated for this conversion?
Cost: 1 credit per 10 MB
How it works:
- Files up to 10 MB: 1 credit (minimum)
- 11-20 MB: 2 credits
- 21-30 MB: 3 credits
- 31-40 MB: 4 credits
- Over 1024 MB: 103 credits (maximum cap)
Example: A 5 MB file = 1 credit. A 95 MB file = 10 credits.
Why per-megabyte? Larger files require more resources (processing, bandwidth, storage).
What are my daily and monthly credit limits?
Credit allocations vary by account tier:

|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
