Crisper Document Scanner
Mac OS Productivity
Scan documents from images into a crisp black and white file
Crisper Document Scanner enables you to extract documents from images with proper perspective correction so that you have a simple black and white "scanned" image.
The images you scan are automatically analysed to look for possible page boundaries.
If a boundary is not found, or you would like to scan a different region, simply drag the end points of the found boundary onto where you would like to have it placed instead.
Simple configuration options allow you to tweak the output for a better match.
Please note that the output scanned images are black and white, so the app is suited primarily towards scanning of text documents and may not be suitable if you wish to scan documents with images in them.
By default, the app overlays a small watermark on the output image and displays ads. However, once you are satisfied with the apps functionality, a single one-time in-app purchase can be used to remove the watermark as well as ads.
