PDF Content Comparer

Intuitive, intelligent comparison of your PDFs.

Your PDFs contain actual content, not just text or images. i-net PDFC intelligently compares the content in your files. Any differences are shown in a visually gorgeous display, akin to holding up two pieces of paper to the light.

Best of all: your data stays on your premises.

i-net PDFC compares lines, shapes, images as well as text

i-net PDFC does not simply do a text conversion or pixel-by-pixel comparison, which both lead to loss of information. We make a deep structure comparison including styles, shapes, and a lot more.

Controlled Sensitivity

Settings for the most needed options

There are not too many options - we only choose the ones that will really matter to you. You still have fine-grained control over every aspect of the comparison. And if you need even more control: the API has you covered.

Export and Report

Export the differences as report or original document with annotations

i-net PDFC lets you create summary reports about the differences in the documents. Additionally, you can print or export your PDFs with highlighted differences as new PDFs. Differences will be added as annotations as well.

Additional Filters

Extend i-net PDFC using a selection filter and OCR plugins

Using additional, optional filters, you can customize the comparison specific to your needs. For example, there is an automatic detection (and manual settings) to avoid too many differences in headers or footers.

Desktop Application

Export the differences as report or original document with annotations

i-net PDFC is a desktop application that is used best by a single user on a single device. It provides full comparison functionality without the management overhead of the Server Application. All files are stored on the users' local computer.

Server Application

Extend i-net PDFC using a selection filter and OCR plugins

The i-net PDFC Server allows multiple users to create comparisons with their own user accounts. They can store files and comparison results, make use of the Task Planner or WebAPI. Data is stored on-premise, with no data being sent to third parties.

Let me say that i-net PDFC is awesome.

We are trying i-net PDF Content Comparer, and I have to say it is so powerful.

- StateStreet

I have evaluated quite a number of different diff tools for comparing PDF documents. Your tool is outstanding for visualizing and synchronizing results - even with many insertions.
