Soda PDF has two different ways that you can review two documents next to each other.
Using the Compare Documents feature, found in the Comment Module, you will find our track changes feature. This is best used when comparing different versions of the same file. Any changes made will be highlighted. Click here to learn more.
Our Side By Side View option lets you simply open up two files next to each other. There are no markings to indicate changes in the document. You can find this in the View Module. Click here for more information.
We have two additional modules. The OCR module allows you to recognize and edit text within any scanned document or image. We also have the E-Sign module that allows you to electronically sign PDFs and track and manage e-signatures in real-time. If those modules are not available for you, you can purchase them here.
