Best settings for a 100KB PDF
Start with the prefilled 100KB target when your portal gives that exact limit. Use recommended compression for clean digital PDFs and stronger compression for scanned certificates, forms, or image-heavy files.
After downloading, compare the output size with the rule from the form, email provider, school, bank, or government portal. Exact-size compression depends on the original images, fonts, and page content.
If the PDF is still too large
Run the file again with a stronger mode, remove unnecessary pages, or compress scanned images before converting them into a PDF. For strict limits, open the downloaded PDF and confirm that names, numbers, stamps, and signatures are still readable.
Keep the original PDF until the receiving website accepts the compressed copy. That gives you a clean fallback if a portal rejects the file or asks for a different size.
