Frequently asked questions
How can I reduce an image file size?
Lower the quality, set a smaller maximum width, or choose a modern output such as WebP.
Will reducing size change dimensions?
Only when you set a maximum width. Otherwise ScanApp keeps the original pixel dimensions.
Is the image stored anywhere?
No. Processing uses local browser memory and the result is downloaded directly to your device.
