About PSE files
The .PSE extension creates a unique challenge because it serves three entirely different sectors: scientific research, enterprise security, and consumer photography.
1. PyMOL Session File (Scientific Visualization): Most commonly, a .PSE file is a session snapshot from PyMOL, a molecular visualization system used in structural biology. These files save the exact state of a 3D environment, including loaded atomic models, camera angles, colors, and ray-tracing settings.
The Problem: These files are strictly proprietary to PyMOL. They cannot be opened in standard 3D software like Blender or viewed in a web browser, making collaboration difficult with colleagues who do not have PyMOL installed.
The Solution: For publication or web use, these should be converted to high-resolution PNG images or ray-traced POV files. If you need to transfer the structural data to other chemistry software, converting the internal molecular data to PDB or CIF is essential.
2. SAP Personal Security Environment (Enterprise IT): In an SAP environment, a .PSE file acts as a secure container for digital certificates and private keys (Personal Security Environment).
The Problem: These are sensitive, binary files. Attempting to open them in a text editor produces garbled data, and they are often locked to specific host identifiers. They are not meant for visual conversion.
The Solution: Administrators manage these using the sapgenpse command-line tool. While you cannot "convert" them to a PDF, you can export the enclosed certificates to standard CRT or CER formats for use in other keystores.
3. Adobe Photoshop Elements Project (Digital Imaging): Less frequently, .PSE refers to project files from older versions of Adobe Photoshop Elements.
The Problem: This format locks your multi-layer compositions into a deprecated or specific ecosystem, preventing you from editing them in modern standard Photoshop or viewing them on mobile devices.
The Solution: To ensure long-term access, these should be converted to standard PSD for editing or flattened to JPG/PDF for archiving.
convert.guru allows you to identify which type of .PSE file you possess and guides you toward the correct conversion workflow to unlock your data.
Use Convert.Guru to open and convert your PSE file.
If you want to convert PSE file to CER, PFX, P12 or WEBP, you can use PyMOL or similar software from the "Molecular Visualization Session" category. In the File menu, look for Save As… or Export….
To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to PSE, try PyMOL or another comparable tool in the "Molecular Visualization Session" category.
The PSE Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our PSE converter.
