What is an LBM file?
The .LBM file extension most commonly represents a Deluxe Paint Bitmap Image. Electronic Arts created this raster image format for the Deluxe Paint software on Amiga computers in the 1980s. It uses the Interchange File Format (IFF) structure. However, an .LBM file can also be a Logic Pro audio file or a compressed graphic asset for old video games by Bullfrog Productions.
Because the .LBM extension has multiple possible meanings, viewer.online/lbm analyzes .LBM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
How to open LBM files?
If your file is an Amiga bitmap image, you can open it with versatile image viewers like IrfanView or XnView MP. Many modern photo editors like Adobe Photoshop or GIMP no longer support this format natively and require special plugins. If your file belongs to an audio project, you must open it using Apple Logic Pro on a macOS system.
Best practices and troubleshooting
When you find an unknown .LBM file, check its context. A small file from an audio studio is likely a Logic Pro file. An old archive from an Amiga disk is likely an image. To make these image files usable in modern software, we recommend file conversion to sensible target formats like .PNG or .JPG on convert.guru.
Summary
viewer.online/lbm directly opens and previews .LBM files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
