Why Compress a PDF for Upload Portals?
Government websites, university admissions systems, job application portals, and insurance claim forms often enforce strict file size limits — sometimes as low as 1MB or 2MB. If your PDF exceeds the limit, the upload fails. OmnisPDF applies extreme compression to drastically reduce your file size, helping you submit your documents without issues.

Common Use Cases
Job Applications
Many job boards and applicant tracking systems limit resume and cover letter uploads to a few megabytes. Compress your application documents so they upload without errors on LinkedIn, Indeed, Workday, and other platforms.
University Admissions
College and graduate school application portals often require transcripts, recommendation letters, and personal statements under strict size limits. Compress your documents to meet these requirements without losing readability.
Insurance Claims
Insurance portals frequently cap document uploads at small sizes. Compress scanned receipts, medical records, and claim forms so they upload successfully to your provider's system.
Government Filings
Tax filings, permit applications, visa forms, and regulatory submissions often have strict upload limits. Compress your PDFs to meet government portal requirements and avoid submission errors.
