How to use Clean scanned PDF
Old scans are often grey, tilted and framed by black scanner borders. This tool straightens each page, evens out lighting, turns the paper white and sharpens the text, so documents are easier to read, print and compress.
Open a scanned PDF and compare the original and cleaned preview side by side.
Choose colour, greyscale or black and white, and the corrections you want.
Apply to all pages or only the ones you select, then download the cleaned PDF.
