Many of your PDF files will contain many different content elements. i-net PDFC is special because it is aware of all of them. Page headers and footers and multi-column layout are detected and handled correctly.

Intuitive Usage

Intuitive Usage

PDF Content Comparer

Comparing is as simple as dragging two PDFs into the compare window and clicking on the compare button. The result is a simple, intuitive overview of any differences detected in the two PDFs.

Instead of only comparing text in the PDFs, or converting the PDFs to images and comparing those pixel by pixel like other comparison tools, i-net PDFC can intelligently compare the actual content elements in your files such as…

  • Text differences
  • Line/Arc/Box differences
  • Image differences
  • Margin differences

These types of differences can each be configured in regards to their sensitivity, making for a powerful, elegant way to compare your documents the way you want to.

i-net PDFC is a pure Java application. This means it runs on any platform with a Java Runtime Environment 71) - nearly every modern platform such as Windows 7, OSX 10.7 or Ubuntu 12.042).

Let me say that i-net PDFC is awesome.

- AppFolio

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.


Key Features


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

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.

Powerful difference views

Intuitively view differences via the synchronized scrolling views side-by-side. Or check the differences as if you where holding two sheets of paper up to the light: semi-transparently one over the other.

Controlled sensitivity

Settings for the most needed options

There are not to many options - we only choose the ones that will really matter to you. You still have fine grained control on 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

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

Exclude the unnecessary

Create text-exclusion expressions - either plain text or regular expression

There is automatic detection (and manual setting) to avoid too many differences in headers or footers. You can even exclude text or regular expression patterns from the comparisons. Concentrate on what is really different in the documents.

Intuitive interface

Display and jump to annotations

The UI will satisfy your every need. Click markers on the scrollbar to jump right in. Select search results or annotations and you'll be brought there. Double klick a marker and get all the changes in plain text. Use the arrow keys to navigate back and forth.

The following features enable you to integrate i-net PDFC into your own environment using build scripts, the API, or your favorite CI tool such as Hudson.
