Now your photos look better than ever – even those dusty old prints

We knew there had to be a better way, so we’re introducing PhotoScan, a brand new, standalone app from Google Photos that easily scans just about any photo, free, from anywhere. Get it today for Android and iOS.

PhotoScan gets you great looking digital copies in seconds – it detects edges, straightens the image, rotates it to the correct orientation, and removes glare. Scanned photos can be saved in one tap to Google Photos to be organized, searchable, shared, and safely backed up at high quality—for free.
