What is a PSE file?
The .PSE file extension is shared by multiple distinct software applications. Most commonly, it acts as a PyMOL Molecular Graphics System session file. These files store 3D molecular structures, visualization states, and annotations used in scientific research.
However, a .PSE file can also be a Photoshop Elements Photo Project created by Adobe Systems, an SAP Cryptographic File containing security credentials, a laser engraving design from EZCAD, or a renewable energy simulation project from Vela Solaris Polysun.
How to open PSE files?
Because the .PSE extension has multiple possible meanings, it is critical to know the file's origin before opening it. You can open molecular session files with PyMOL. Photo projects require Adobe Photoshop Elements. Laser designs need the EZCAD laser control software.
Inspection and Conversion
To avoid guessing the file type, viewer.online/pse analyzes .PSE files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
If you need to share the file in a more standard format, we recommend file conversion to sensible target formats on convert.guru. Depending on the original file type, you can convert it to .PDB for molecular data, or .JPG and .PNG for photo projects.
Summary
viewer.online/pse directly opens and previews .PSE files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
