Before you compare

Compare two Word documents, two Excel workbooks, two PowerPoint presentations, or two eligible PDFs. Check PDF requirements before choosing your files.

For presentations, RedlineIQ shows changes to slide text, speaker notes, tables, and pictures. It also shows inserted slides, removed slides, and changes to slide order.

Online comparisons process your files in the cloud. Your redlines are private, and download access expires after 24 hours. Storage cleanup and backup retention follow our privacy policy.
