What it does
A pocket scanner that makes real PDFs
ScannerFlow is built for the moment you have a piece of paper and need a digital copy that looks professional — not a crooked, shadowy phone photo.
Auto edge detection
The camera finds the page outline and straightens the perspective so every scan is square and crop-perfect.
Scanner-grade enhancement
Filters remove background, even out lighting, and sharpen text so a photo reads like a flatbed scan.
Multi-page PDFs
Add, reorder, and delete pages, then export the whole document as one tidy PDF you can send anywhere.
How it works
From paper to PDF in four steps
The whole flow happens on your phone — capture, clean up, and export without a desktop.
- 1
Open ScannerFlow and tap scan
Launch the app and tap the camera button. Lay the document on a flat, contrasting surface for the cleanest capture.
- 2
Let auto-crop find the edges
ScannerFlow detects the page borders in real time and straightens the perspective. Nudge the corners manually if you want a precise crop.
- 3
Enhance and add pages
Pick a filter — color, grayscale, or high-contrast black-and-white — to sharpen the text. Keep scanning to stack as many pages as you need into one file.
- 4
Save as PDF and share
Tap Save to export a clean PDF, then send it straight to email, cloud storage, or any messaging app on your phone.

Scan-to-PDF FAQ
How do I scan a document to PDF on my phone?
Open the ScannerFlow app, tap the scan button, and point your camera at the page. The app auto-detects the edges, captures the page, and applies an enhancement filter. Add more pages if you need a multi-page file, then tap Save to PDF. Your scan is ready to share in seconds.
Is ScannerFlow free to use?
ScannerFlow is free to download and free to try. You can scan and export single-page PDFs right away. A subscription unlocks multi-page PDFs, batch scanning, and cloud sync. You can review the plans inside the app before committing.
Will the scanned PDF look like a flatbed scan?
Yes. ScannerFlow corrects perspective, removes the background, sharpens text, and evens out lighting so a photo of a page comes out looking like it was run through a desktop scanner — no shadows, no skew, no curled corners.
Can I scan multiple pages into one PDF?
Absolutely. Keep tapping the shutter to add pages, reorder them by dragging, delete any you do not want, then export the whole stack as a single multi-page PDF. Multi-page export is part of the subscription.
Are scanned PDFs searchable?
ScannerFlow runs on-device OCR so the text inside your scan can be recognized and extracted. If you mainly need editable text, see our image-to-text page for the OCR workflow.
Does it work on Android?
Yes. ScannerFlow is available on Android via Google Play, with a fast, reliable scan-to-PDF workflow.
