Convert SGI to PNG

Understanding SGI and PNG file formats

SGI (Silicon Graphics Image) is a raster graphics file format developed by Silicon Graphics, Inc. It is commonly used for storing bitmap images, especially in high-end graphics workstations. SGI files support both grayscale and color images, and can include an alpha channel for transparency.

PNG (Portable Network Graphics) is a widely used raster image format known for its lossless compression and support for transparency. PNG is ideal for web graphics, digital artwork, and images requiring high quality and transparency.

Why convert SGI to PNG?
