About the product

ComparePDF is a free, privacy-first online tool for comparing two PDF files. It helps users identify text and visual changes across contracts, business reports, policies, invoices, proposals, and scanned documents. Unlike traditional cloud-based document comparison services, ComparePDF processes files locally inside the user's browser, so sensitive documents are not uploaded to or stored on a remote server. Users can review pages using side-by-side, overlay, slider, and difference views, while selectable-text analysis and English OCR help surface content changes. The product requires no account or software installation and supports PDF files up to 25 MB each. ComparePDF is designed for professionals, small teams, students, and anyone who needs a fast way to review document revisions while maintaining control over confidential files.
