What is the .pl file extension?

The .pl file extension is associated with 3 different software ? Perl, Prolog and BRL-CAD. Perl and Prolog use the .pl extension extensively to save the source code while BR-CAD uses them to save images in 2D and 3D image plots.

Let?s have a look at the uses of the .pl file extension in detail ?


Perl is an open source high level programming language that is used majorly to design scripts. It is a very dynamic programming language that has influenced other popular languages like PHP, Python, Ruby and JavaScript. All scripts created in Perl are saved using the .pl file extension and these scripts are used to parse text using expressions.

The .pl file extension is seen rarely on web pages as they are usually served as .cgi files. Although Perl is not inserted into static web pages, they can be clubbed with CGI libraries to generate specialized functions. Over the years Perl is also used for ?

  • Network programming
  • Design? GUI?s
  • Web development
  • Bio informatics


It is a powerful logic programming language that is used widely in the field of Artificial Intelligence. It is a declarative language where the logic is determined on relations and is represented by facts and specified rules. The files created using this language are stored in the .pl file extension format. Even though this was one to the first logic programs designed, it still is one of the most popular software used today and GUI variants of this software are also available.


BRL-CAD is a powerful open source software used to create solid modeling computer aided design. 2D and 3D image plots are stored in the vector image format and carry the .pl file extension. Files with the .pl file extension are converted into .png files using the converter software present in BRL-CAD.
