SAI File - opening and understanding

Did your computer fail to open a SAI file? We explain what they are used for and recommend software that we know can open or otherwise handle your .SAI files.

What is a SAI file?

The .sai file format is an image file type generated by using the PaintTool SAI software. A SAI file contains drawings made by the user. It is also composed of multiple independent editing layers made from creating more complex artwork form.

Developed and published by SYSTEMAX Software, PaintTool SAI is a lightweight raster graphics editor and painting software with various drawing tools that are not common to other paint tools. It is designed to run on Microsoft Windows series. The stable version of software (v1.2) was officially released in the first quarter of 2014.

Edited paintings and new projects made by using the PaintTool SAI are often saved in .sai format, which can also be exported to .psd format when the user wants to edit it using Adobe PhotoShop. Moreover, .sai files are proprietary in nature. Opening them in other image editing software may not be possible without exporting them in another format or without using the software mentioned above.
