How to compress a PDF to 100 KB
Some portals cap every upload at 100 KB. This page is set to find the sharpest version of your PDF that still fits. One- or two-page scans usually fit easily; for longer documents, upload only the pages the form asks for.
Add the PDF (or several).
Check that 100 KB is selected, or type another limit.
Click Compress PDF and download the file that fits.
