What are the file size limits for PDF checking?

Our PDF authenticity checker accepts PDF files up to 10 megabytes (10 MB) in size. This limit ensures fast analysis and optimal performance for most common PDF documents including contracts, certificates, invoices, reports, and academic documents.

Files exceeding this limit will be rejected with an error message. If you need to check larger PDF files, consider splitting them into smaller documents or compressing the PDF before upload.

The 10 MB limit applies to the original file size before any processing. Our free PDF verification service is designed to handle typical document sizes efficiently while maintaining quick response times and reliable analysis results for PDF modification detection.
