What is a RIFF file?

An RIFF file is a raster image image saved by Corel Painter, a digital art studio used to create digital paintings. It stores image data, including Painter elements, such as pencil sketches, brush strokes, and shapes. Painter saves images more commonly with the .RIF extension.

Corel Painter is a tool casual and professional artists use to create digital paintings. The program creates RIFF files to preserve an image you are working on, allowing you to close the project and re-open it to continue editing it.

RIFF files retain all the project information. Also, RIFF files store Painter elements separately from the canvas so that artists can customize the canvas later.

How to open a RIFF file

You can open a RIFF file with Corel Painter (Windows, Mac). To do so, select File → Open... from the program's menu bar.

  • .JPG - JPEG Image

A RIFF file may also be a raster image saved in a proprietary format developed by Fractal Software. It contains a grayscale or color image. Letraset ImageStudio and ColorStudio create RIFF files.

More Information

Letraset ImageStudio and ColorStudio are image editors for old Macintosh computers. ImageStudio allows users to create and edit grayscale images. ColorStudio allows users to create and edit color images (which can contain CMYK or RGBA color data). Both programs save images users have created as RIFF files.

RIFF files may be compressed or uncompressed. Uncompressed RIFF files open more quickly in ImageStudio and ColorStudio. However, they also have much larger file sizes than compressed RIFF files. Compressed RIFF files typically have much smaller file sizes than comparable .TIFF files.

NOTE: While Letraset published ImageStudio and ColorStudio, Mark Zimmer of Fractal Software developed the RIFF file format.

How to open a RIFF file

You can open a RIFF file with Letraset ImageStudio (Mac) or Letraset ColorStudio (Mac). Note that ImageStudio cannot open color RIFF images.
