Top 5 PDF Compare Tool to Compare PDF Files [Online and Offline]

Comparing two PDF files manually can be tedious and time-consuming. It could take days, based on the volume. This further stress the importance of a PDF compare tool. 

How to Compare PDF Files with Adobe Acrobat

Adobe Acrobat is a popular software among PDF users. It has lots of PDF editing tools like merging, compression, encryption, signatures, etc. Acrobat is the industry leader in PDF editing tools, and it is liked because of its ease of use and wide array of features. It is available for both Windows and Mac and comes as a part of the Adobe Suite, which is pretty expensive. For this tutorial, we will be using Adobe Acrobat Pro 2017.

The steps to use Adobe Acrobat to compare PDF files are as follows:

Step 1. Go to the "Tools" tab and select "Compare Files".

Step 2. Now Adobe Acrobat shall show you a page where you have to select your old PDF and new PDF which you want to compare. On this screen, Adobe also shows you a checkmark that allows you to compare only the text of the 2 PDFs you have selected.

Step 3. You can also edit some settings by clicking on the "Settings" text. This allows for settings like which pages to compare in both PDFs. Now, click on "Compare".

Step 4. Now Adobe will show you a summary of the differences between the two files. You jump to different pages by clicking on the "Next Change" button.

And that's how to compare 2 PDF files using Adobe.

If Adobe seems very expensive to you or very complex, then don't worry. Now we will show you how to compare 2 PDF files using an online PDF comparison tool. The website we will be using is called Draftable. It is a document comparison service that has an online tool. This online tool can not only compare PDFs, but it can also compare Word documents or even PowerPoint presentations. The steps for this tool are:

Step 1. Upload the 2 PDF files you want to compare and click on the "Compare" button.

Step 3. Here you can see the difference between the 2 PDFs in the sidebar. You can only view the changes in the content of the 2 documents or even in the style of the 2 documents.

Draftable's online tool is free, but there are some limitations. First, the maximum file size is 10MB, so you will have to compress your PDF if it is above 10MB. Secondly, your PDF page can't contain more than 300 pages in your PDF.

If you want more features, then you will have to upgrade to Draftable Desktop.
