Utilities to compare files and convert documents

At Softinterface, we offer powerful document conversion and file comparison tools for the most widely used file types. PDF, Word, Excel, Text, CSV, HTML, JPG, TIF for example. Built for ease of use, power and maximum flexibility, our tools will help you streamline your workflow by automating repetitive tasks in your workplace.

Why Do I Need Document Conversion Tools?

Very often you've just installed a particular software package but can't access the data because it is not in the required format. You need a conversion tool that will change your file from one type to another. That's where we can help. We've developed file conversion and manipulation tools for documents (such as PDF, DOC, DOCX, RTF, HTML and XML.), spreadsheets (XLS and XLSX), images (TIFF, JPG, BMP and GIF) and text files (TXT, CSV).

Another reason is that you have two software applications that need to communicate but can't due to different file formats. Converting files from one format to another will solve this problem. Automating this conversion of files is exactly what our tools were designed for. Use the command line with any of our tools for quick integration.

Why Document Comparison Software?

Today people use different kinds of document types all day long to collaborate and work together on projects across all industries. These files can be modified by the original author, or by colleagues. Detecting differences in small files can be relatively easy. However when the files become larger and more complex, detecting changes can become more difficult. That's where our software comes in handy, making detecting changes a simple one. 'Diff Doc', the world's first comprehensive document comparison tool, was built to compare files of all types including PDF, Word, Excel, PowerPoint, HTML, XML, RTF, Text and more. This is very important especially with legal and accounting documents. The length and complexity of real estate mortgage documents are a classic example of how small changes in very large documents could have serious implications. With our tool at your side there won't be any worries.

Automating the Office Drudgery?

Do you find yourself doing a document comparison or document conversion in the same way day after day? Perhaps you have so many files that you need to compare or convert that doing it one by one is simply not reasonable. In both of these situations, using well-designed software technology can enhance your productivity. Automate your workplace by removing repetitive tasks from your workflow.

Why Choose Us?
