Compare two PDFs

Sometimes we have this situation when we need to compare two very similar PDF. In my case, I have a lot of comparing work with my business contracts versioning. Instead of scanning all documents separately and manually I use tools.pdf24.org/fr/comparer-pdf service to do it automatically. Please find below a short video of how does it work.

Demo of the solution

Results

The service is quite accurate for very similar documents. Almost all differences between two very similar documents are identified.

However, when you compare very different documents it becomes less useful.

Below you will find a screenshot (first page) of the output from comparing two very similar business contracts (in red = words erased; in new green = new words).

Performance

Usually, it takes 5-10 seconds but sometimes it can take > 1 min to come up with the results.
