How to compress a PDF to 100KB

Use a clean source PDF

Text-heavy PDFs usually reach 100KB more easily than scan-heavy files.

Increase compression gradually

Start with medium compression, then increase only if the output is still above the target size.

Re-export if needed

If the PDF stays large, remove extra pages or oversized scans, then compress again.
