"We want to avoid any unnecessary steps in our review processes. By using Acrobat to convert materials to PDF for improved collaboration, we’ve cut document review cycles in half."

Compare two versions of almost any file

Whether you need to compare two versions of a legal document, PowerPoint presentation, or any other file, convert them both to PDF. Then use the file compare tool to pinpoint changes.

Changes can’t hide

If just a single word has changed from one version of a file to the next, Acrobat XI will find it. So you'll never have to check your files line by line again.
