Convert LFM to another file type
To convert your LFM file to another format, you need Lazarus IDE or other Developer software.
Convert a file to LFM
To convert other file formats to the "GUI Layout Definition" file type, you need software like Lazarus IDE or a similar tool.
About LFM files
The .lfm extension is a fragmented format used by three distinct industries, creating significant confusion for users trying to open one.
Lazarus Form File (Developer): The most common variant is a text-based GUI definition used by the Lazarus IDE. It describes the layout of buttons, windows, and labels in a Free Pascal application. While these are technically plain text, they are often unrecognized by standard editors, requiring you to manually associate them or install a heavy IDE just to view code.
Leica Cyclone Scene (3D/CAD): In surveying and engineering, an .lfm file acts as a pointer or metadata file within the Leica Cyclone ecosystem. These files reference massive laser scan datasets. Users often struggle here because the .lfm file alone does not contain the 3D points - it links to a database. You cannot simply "open" this in AutoCAD without the connected project folders.
Label Designs (CAS/Labeljoy): Various labeling software, including Labeljoy and CAS, use .lfm for saving proprietary sticker layouts. These are strictly locked to their parent software and cannot be edited elsewhere.
Conversion Solutions:
For Lazarus files: Convert to TXT to edit in any code editor, or PDF for documentation and code review.
For Leica files: You generally need to export the project from Cyclone to E57, LAS, or PTS to make the data usable in Revit or Blender.
For Labels: The only practical conversion is to JPG or PDF for proofing, as the layout logic is proprietary.
Convert.Guru analyzes your LFM file, detects the exact format, and lets you read the text inside.
If you want to convert LFM file to CFM, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Lazarus IDE or similar software from the "IDE Form Definition" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to LFM, try Lazarus IDE or another comparable tool in the "IDE Form Definition" category.
The LFM 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 LFM converter.
