Reduce the resolution. Generally scanning a document at about 300dpi is the right combination of lower file size and legibility. Scan in black and white (bilevel). This saves both time and space. Most scanners can scan faster in black and white than t can in color so youâll get your scans faster and smaller files. Use PDF compression. Most scanner software will do this by default but if you have the option make sure you select it. To show you how much space this can save I scanned the same 1 page document with our scanner software VueScan 600 DPI Color - 1.1 MB 300 DPI Black and White - 7 kB (99% size reduction) And the more pages you are scanning the more important it is to reduce the file size.
