Compare PDF Files

The Document Compare feature lets you see the difference in two versions of a PDF, as well as select the type of differences you’re looking for to verify that the appropriate changes have been made. The Document Compare feature does not compare comments in the PDF.

Comparing a revised PDF to an earlier version

• Choose View tab > Compare (or Review) group > Compare.

• Specify the two documents to be compared. Click Choose… to select the file and choose the specific pages you want to compare by dragging the slider or clicking the list box to select the page number.

• Type of Comparison:

Page by page visual differences – Compares by visual differences, including texts, images, annotations, etc.

Textual differences – Compares texts only between the two documents, not including comments. Check Include font information (style, size, typeface) if needed. You can also set to highlight differences when documents differ by less than a percentage to easier find out the differences.

Include page reassembled changes – If you check this option, the application will automatically ignore the textual differences if some of the pages were replaced, deleted, or inserted, and will indicate that the pages were replaced in the comparison result.

• You can preview pages after you check Show preview option. Choose the specific page you want to preview by dragging on the page range bar or select the page number by clicking the list box near the range bar.

• Click OK. And then a PDF document named “The result of Comparison.pdf*” will be automatically created and opened with PhantomPDF. The first page shows a summary of the comparison results and the differences will be classified with different colors.
