Why compress PDF to 100KB?
Some upload systems have brutally strict file limits. Indian government portals, certain banking document uploads, and legacy application systems sometimes demand PDFs under 100KB or even 50KB. While extreme compression does affect image quality, for text-heavy documents like forms, resumes, and certificates, you can often hit these tiny targets while keeping the document perfectly functional. AskPDF's ultra-compression mode is designed for exactly these situations.
