Frequently Asked Questions
How much fits in 100 KB?
About one or two scanned pages that are still readable. A PDF with only typed text and no pictures is often already smaller than 100 KB.
How do I get a better result from my scanner?
Scan at 150 to 200 DPI in black and white or grayscale, and crop away empty margins. A colour scan at 600 DPI starts far too big.
What if it is still over 100 KB?
Split the PDF with Split PDF and compress each part, or check whether the form accepts 200 KB.
