Frequently Asked Questions: Compressing to < 200 KB
Why target 200KB for PDF documents?
200KB is the default maximum upload threshold for government visa portals (e.g., US, UK, Canada, India), banking KYC verification, and e-filing systems.
Can multi-page PDFs fit under 200KB?
Documents between 2 to 5 pages with text and black-and-white or small color figures consistently compress below 200KB using our 120 DPI profile.
How does PDFMill guarantee file safety?
We never transmit files over any network socket. The computation runs entirely in client WebAssembly and JavaScript.
