Can I scan multi-page documents into one PDF?

Yes. All apps in this list support multi-page scanning into a single PDF. After scanning the first page, tap to continue scanning additional pages before converting to PDF.

Is Adobe Scan free?

Adobe Scan is free to use for basic scanning with an Adobe account. OCR is included free. Converting scanned PDFs to editable Word documents or accessing other advanced features requires an Adobe Acrobat Pro subscription.
