Which file format is commonly produced by most digital cameras for easy use online or via email?

The JPG file format, also known as JPEG (Joint Photographic Experts Group), is commonly produced by most digital cameras primarily because of its efficient compression method. This format reduces file size significantly while maintaining a good balance of image quality, making it ideal for online use and sharing via email. The compression process allows for faster uploads and downloads, which is essential in an era where large image files can be cumbersome in terms of storage and bandwidth.

In contrast, other formats such as TIF (Tagged Image File Format) involve less compression and often result in much larger file sizes, making them less suitable for online sharing or sending through email. RAW files, produced by many cameras, maintain all the unprocessed data from the sensor, providing the highest quality for editing but resulting in very large file sizes that are impractical for quick sharing. GIF (Graphics Interchange Format), while good for simple graphics and animations, does not support the same level of color depth and detail as JPG, making it less suitable for photographs.
