7 free and paid services for comparing documents

Comparing documents manually is very time consuming and prone to errors. You can find changes in different versions of a document in Word or Excel, but it is more convenient to do this through special services for comparing documents. Here are some free and paid tools.

Diff checker – Free document comparison service

The service only works with PDF files or copied text. To check the changes in the document, you need to paste both versions into a special field – the comparison results are displayed at the top.

In the free version, when comparing documents, the service clears the formatting by default.
