FAQ

No. The tool fully preserves all illustrations, photos, charts, and tables from the original PDF, ensuring the converted e-book content matches the original document.
Yes, they can be converted. However, since scanned PDFs are essentially images, the text in the output will not be selectable or searchable. For editable EPUBs with text, we recommend using an OCR tool to recognize the text before conversion.
Individual files up to 50MB are supported. For very large PDF e-books, we recommend splitting them into smaller files using a PDF split tool before conversion.
Most files complete in seconds to tens of seconds, depending on the page count and content complexity. You can track real-time progress during conversion — no long waits required.
The tool intelligently analyzes the original document's layout structure and adapts it for e-book format automatically. Text-heavy PDFs yield the best results; multi-column or complex mixed layouts may show slight deviations, which is normal.
Completely secure. This tool uses local processing technology — all file conversion happens entirely in your browser. Nothing is uploaded to any server, and no traces are left after conversion, fully protecting your privacy.
