Convert RIFF to JPEG

Understanding RIFF and JPEG file formats

RIFF (Resource Interchange File Format) is a generic container format developed by Microsoft and IBM. It is primarily used to store multimedia data such as audio, video, and images. RIFF is the basis for several specific file types, including WAV (audio), AVI (video), and WEBP (image). However, RIFF itself is not an image format, but a container that may include image data in a specific sub-format.

JPEG (Joint Photographic Experts Group) is a widely used compressed image format known for its efficient lossy compression, making it ideal for photographs and web images.

How to convert RIFF to JPEG

Since RIFF is a container, the actual conversion process depends on the type of data stored within the RIFF file. If your RIFF file contains image data (such as a WEBP image, which uses the RIFF container), you can extract and convert it to JPEG. If the RIFF file contains audio or video, conversion to JPEG is not meaningful.

Best software for RIFF to JPEG conversion

The most common scenario is converting a WEBP (RIFF-based) image to JPEG. The following tools are recommended:

• IrfanView (Windows): Open the WEBP file, then use File → Save As and select JPEG as the output format.
• XnConvert (Windows, macOS, Linux): Batch convert WEBP (RIFF) images to JPEG easily.
• Online converters: Websites like Convertio or CloudConvert support WEBP to JPEG conversion directly in your browser.

Step-by-step conversion using IrfanView

1. Download and install IrfanView.
2. Open your RIFF-based image file (e.g., WEBP) in IrfanView.
3. Go to File → Save As.
4. Select JPEG as the output format.
5. Click Save to complete the conversion.

Important notes

• If your RIFF file is not an image (e.g., WAV or AVI), it cannot be converted to JPEG.
• Always check the file extension and content before attempting conversion.
