The rapid, widespread, and by now nearly complete, adoption of PDF-based workflows over the last decade has eliminated many of the issues that came with previous approaches. Delivering PDF files gives content creators a lot more control over their work than they ever had before.
This increased control can have disadvantages as well as advantages. Along with the control comes a much higher level of responsibility. If the content of a PDF file you deliver contains an error, it may be your responsibility!
Each time you generate a new PDF file, it’s critical to know that all desired changes have been made, and, just as importantly, that no unwanted changes have crept in; PDF Comparator makes quick work of both!
Unlike many other tools, that compare two PDF files’ text or image content, PDF Comparator actually renders each page to a raster image, and then compares those images on a pixel-by-pixel basis, ensuring that the comparison is made on how the pages will actually print.
