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.
