A pre-press producer often has to proofread a document. The usual way is to open the source on the left, open the manuscript in production on the right, then carefully look for differences. The overall process is really tedious, lengthy, eye-straining, energy-consuming, maddening, and most often there are omissions. If you often have to compare PDF documents at work, DiffPDF can help you finish the document comparison work easily and efficiently.

DiffPDF is able to automatically analyze, find all the differences in both text and layout aspects (the latter mainly refers to images) between two PDF files, highlight the different areas with colors, and output the comparison results as a readable report. In addition, it supports filtering content by image, text, annotation or format, and directly displaying the result of comparison in a list for better viewing.

DiffPDF offers two comparison modes, "Text" and "Layout". It can display page comparisons between two PDF documents and highlight any differences; or the pages can be compared based on text, regardless of the layout and appearance (including font, color, layout, charts, images, etc.). For PDF documents with images, choosing the "Layout" comparison mode will give you more accurate results.
