What is a SML file?
A .SML file is a file extension with several very different uses. Most commonly, it is a Publication Supplementary Graphic file downloaded from the Elsevier ScienceDirect platform. These files are actually standard GIF images that contain charts, graphs, or visual data for scientific research papers.
However, .SML files have many other uses in software and technology. They often store Standard ML source code used by software developers with SML/NJ. They can also be Sensor Model Language files written in XML for the Open Geospatial Consortium, or an ARC/INFO Simple Macro Language File used by GIS software from ESRI. You might also find .SML files used as smart meter data logs from companies like EnBW, or as mod packages for the PC game Stoneshard.
How to open SML files?
Because the .SML extension has multiple meanings, you must know the exact file type before you open it. If it is an image from an academic paper, any modern web browser or image viewer can open it if you manually rename the file extension to .GIF.
If it is a developer script, XML data, or an ARC/INFO Simple Macro Language File, you can view the text in a code editor like Notepad++ or Visual Studio Code. For specialized data, like energy meter logs or game mods, you need the specific software that created the file.

Because a .SML file can be an image, source code, or binary data, you should not guess its format. Instead, viewer.online/sml analyzes .SML files to identify their exact format and creator software, shows which programs can open the file, and usually previews it directly in your browser.
Summary
While this file extension is shared by many different applications, academic images are the most common use. Because these specific .SML files use the known GIF format, viewer.online/sml can safely open and display them online, eliminating compatibility problems.
