About this app

Pi Scanner is a fast, private document scanner for paper you need to keep, share, or search.

Point the camera at a page. Pi Scanner finds the edges, waits until the shot is steady, and captures automatically. Skewed or angled photos are flattened into a clean, top-down scan. Scan many pages in a row into one PDF without breaking your flow.

Built for real paper
• Auto edge detection and hands-free auto-capture
• Perspective and skew correction
• Batch / multi-page capture
• Blur and quality check with a retake prompt
• Import photos from your gallery

Image enhancement

Edit, sign, and share
