Scan to PDF
Turn any paper document into a professional PDF in seconds. Choose from multiple quality presets, create multi-page documents, and share instantly.
The right size for every situation
Not every PDF needs to be the same size. A document you email to a colleague should be small enough to avoid inbox limits. A document headed to a professional printer needs full resolution. A receipt you text to a friend just needs to be readable. ScanFlow gives you three presets so you never have to think about compression settings.
Email Ready produces compact files, typically under 1 MB per page, that look sharp on screen while staying well under email attachment limits. Print Ready preserves the full resolution of your scan for professional-quality printing at 300 DPI and above. Quick Message creates the smallest possible file for fast sharing over messaging apps, optimized for mobile screens.
Combine pages into one document
Scanning a multi-page contract, a stack of receipts, or a complete notebook is straightforward with ScanFlow. The continuous scanning mode keeps the camera active between pages, so you can work through a stack quickly. Each page is processed individually for optimal quality, then assembled into a single multi-page PDF.
Already have separate scans that belong together? The Merge feature lets you combine any number of existing scans or PDFs into one unified document. You can reorder pages by dragging them into position, rotate individual pages, or remove pages you do not need before creating the final merged PDF.
Export formats and options
ScanFlow's primary export format is PDF, the universal standard for document sharing. Every scan produces a PDF that is compatible with any PDF reader on any platform. The PDF files are compliant with the PDF/A archival standard when using Print Ready quality, ensuring long-term readability.
Beyond PDF, ScanFlow also supports exporting scans as JPG images, which is useful for inserting scans into presentations, documents, or social media. If you have used OCR to extract text from a scan, you can export just the recognized text as a plain text file for easy copying and editing.
The sharing workflow is designed for speed. After scanning, you can share directly to email, messaging apps, AirDrop (iOS), or any other sharing target available on your device. The Quick Share option in the scan results screen lets you send the document in just two taps. For regular workflows, you can set a default export quality so the app remembers your preferred settings.
For users who need to annotate before sharing, ScanFlow includes markup tools that let you add text, highlights, and signatures directly on the PDF before export. This means you can scan a contract, sign it, and email it back, all within a single app without switching between tools.
