A Guide to the eViewer Document Compare Tool

In today’s fast-paced digital world, users need a quick and accurate tool to compare different file formats in one place. The tool must be capable of reviewing, comparing, and displaying all the results between the documents, while also allowing customization. It is challenging to add custom and user-friendly document comparison functionality to an existing web application. While there are few pre-made components available in today’s market, relying only on cloud-based solutions won’t allow you to have full control of the workflow. On the other hand, creating a solution from open-source software requires significant time and resources for integration, testing, and deployment, and maintaining it in-house will be an even bigger challenge.

This is where eViewer HTML5 document viewer excels, which offers a robust web-based document compare solution that allows users to review, and compare text, images, graphics, annotations, and formatting changes in them.
