What is an LPP file?
An .LPP file is most often a Link Planner Project file used by Cambium Networks LINKPlanner. Network engineers use this software to design wireless network links. The software saves these project files using standard BZ2 data compression.
However, the .LPP extension has multiple possible meanings. It can also be a LabelPrint Project File created by CyberLink for disc labels, or an XML-based project file for LightScribe System Software. In some engineering contexts, it acts as a laser cutting program for TCI Laser machines or a lighting design plot from Lightwright. Occasionally, it is simply a renamed PDF document.
How to open LPP files?
Because the .LPP extension is shared by many different applications, you must identify the correct file type first. You can use viewer.online/lpp to analyze your .LPP file. The tool identifies the exact format and creator software, shows which programs can open the file, and usually previews the content.
If your file is a wireless link project, you will need Cambium Networks LINKPlanner. Since these files use BZ2 compression, you can also use archive tools like 7-Zip to extract the internal data. If the file is a disc label, you can open it with CyberLink software or read the raw XML data with a text editor.
Best practices and troubleshooting
If you cannot open your file, do not guess the software. Use an inspection tool to check the file header. If you need to share the file with someone who does not have the original software, consider file conversion. You can convert the file to sensible target formats like PDF or XML on convert.guru.
Summary
An .LPP file can serve many different purposes, from wireless network planning to disc labeling. Because .LPP files use the known BZ2 format, viewer.online/lpp can safely open and display them online, eliminating compatibility problems. If your .LPP file has multiple possible meanings, we recommend using viewer.online/lpp to identify the actual format of your specific file.
