Frequently Asked Questions

Can I reduce a PDF to under 100KB without ruining it?
Often, yes. Text-heavy files usually compress well. If the PDF includes large images or scans, use a cleaner source or remove nonessential pages for better results.
Does this also help with 75KB or 80KB limits?
Yes. People searching for 75KB, 80KB, or 90KB limits usually need the same workflow: compress hard, check size, and iterate if the portal is especially strict.
What documents usually fit under 100KB?
Short resumes, one-page forms, identity proofs, and text-first PDFs are the most likely to fit comfortably under 100KB.
