Black and White Noise Remove

reaConverter includes a feature designed specifically for correcting noise in black-and-white scanned documents. Digital text files can be retouched so as to improve quality and reduce size.
Scanning black-and-white documents can sometimes result in poor quality digital files, including a grainy or dark image, lack of clarity in rendering letters, or even unreadable segments. Moreover, they tend to have an enormous size and thus be difficult to store. Reasons can vary from the quality of the scanner to that of the document itself.

Load one or more black-and-white scanned documents by using the drag-and-drop tool or by adding them manually.
