About NLM files

The .NLM file extension represents two very different eras of computing history. Primarily (75%), these are legacy Nokia Logo files generated by LogoManager, a popular tool from the early 2000s used to customize Nokia handsets like the 3310 with operator logos and startup graphics. These files are typically monochrome (1-bit) bitmaps. The major constraint users face today is that modern image viewers like Microsoft Photos, Adobe Photoshop, and web browsers render them unreadable, effectively locking your pixel art nostalgia in a proprietary box.

Alternatively, an .NLM file may be a UMLS Metathesaurus data package from the National Library of Medicine. These are often just ZIP compressed archives containing medical terminology datasets. Users encountering this variant often struggle because standard text editors cannot parse the compressed structure.

Best Conversion Targets:

For Nokia Logos: Convert to PNG or JPG to view the graphics on modern screens or share them on the web.
For Medical Data: If the file is an archive, rename it to ZIP or extract the contents to TXT or CSV for database analysis.

Use Convert.Guru to open and convert your NLM file.

The NLM 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 NLM converter.
