Compare Documents Quickly, Reliably, and Effortlessly

Avoid the long, tiresome process of comparing text in two documents line by line. FineReader PDF detects the differences between two versions of a document within seconds. It accurately identifies relevant changes to the text without additional conversion steps, even if the versions of the document are in different formats such as Microsoft Office, digital PDF, scanned PDF, or even other scan and image files.

Focus on the most important differences

Focus on the Most Important Differences

FineReader will only display the differences that affect the meaning of the document and disregard insignificant differences such as formatting or line breaks. This lets you review documents 5 to 20 times faster* so you can focus on what is most important, simplify your work, and reduce the chances of missing something that matters. You can even manually disregard differences that are not relevant for your task, and they will no longer appear in the list of comparison results.

Export and Share Comparison Results

Tailor comparison results to your needs. If someone needs to approve or edit the changes, export to Microsoft Word in Track Changes mode. Or use a PDF with the differences marked as comments to share and discuss with others. You can even save a list of the differences themselves in a Microsoft Word table to have an overview for your records, reports, or discussions.
