What is a RIFF file?
The .RIFF file extension primarily represents the Resource Interchange File Format. This is a generic multimedia container format created by Microsoft. It acts as a standard wrapper for audio and video data. Common file formats like .WAV and .AVI use the RIFF structure.
A .RIFF file can also be a Painter Raster Image associated with Corel, or a Raster Image File Format created by Fractal Software. Because .RIFF has multiple possible meanings, we recommend using viewer.online/riff to identify the actual format of your file.
How to open RIFF files?
If your .RIFF file contains audio or video data, you can open it with standard media players like VLC media player. If it is a Painter Raster Image, you need graphics software like Corel Painter. For command-line inspection of multimedia containers, you can use FFmpeg.
Inspecting files with viewer.online
viewer.online/riff analyzes .RIFF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Summary
Because .RIFF files use the known RIFF format, viewer.online/riff can safely open and display them online, eliminating compatibility problems.
