Important notes:

ReadFlow is a document conversion tool. Conversion quality may vary depending on the structure and quality of the original PDF. Scanned, image-heavy, complex-layout, or damaged PDFs may require more processing and may not always convert perfectly.

ReadFlow does not provide payment card processing directly. Purchases are handled securely through Google Play Billing.

Uploaded files are processed to generate previews and EPUB exports. Please review our Privacy Policy for details about file processing, account data, purchases, and data retention.

What’s new

Improved EPUB compatibility and export reliability.

ReadFlow now generates unique EPUB identifiers so external readers like Kobo can import multiple exported books correctly. This update also improves OCR decisions by checking native PDF text before using OCR.
