DiffPDF

Comparing two documents can be a hassle, both in real life, and on the computer. Carefully sifting through each and every detail to spot any differences is bound to make for a somewhat menial job. Granted, it might be a little easier on the computer, but you'll still have to manually analyze each document.

Luckily, tools capable of comparing two PDF documents automatically exist to make life easier, and DiffPDF is such a solution. Upon inputting their documents and choosing the preferred comparison mode, the program will analyze and point out any existing differences.

The main use case for such a program is pretty clear-cut: if you've got a few documents you wish to compare, you can rely on this one to help with the process. Inserting the documents you wish to compare will display previews for both, so you can also inspect them yourself.

When it comes to the comparison itself, there are a few ways to go about it. Three modes are available, and their naming designates their prerogatives: Appearance, Characters, and Words. It should go without saying that, for documents with lots of visual elements, using the Appearance mode would be best, while those heavy on text would much rather benefit from either of the two modes.

Upon completing the scanning process, which shouldn't take more than a few seconds, the software will highlight any dissimilar passages within the two documents. Users will also be provided with a difference percentage, which can help nudge them in the right direction.

Downloading a report of the highlighted differences is possible after scanning, which can be of use when it comes to redacting the respective documents.

DiffPDF does exactly what it sets out to do: it compares two similar documents to spot any existing differences, and reports them to the user right away
