Why do cameras use JPG instead of PNG?

Is EXIF data from cameras supported by JPEG or PNG? PNGs can't embed the EXIF data that digital cameras use to list a photograph's key details. However, JPEG files can store and display this data, which can include things like the shutter speed and focal length used to take a particular photograph.

What file format does a DSLR use?

Depending on the option selected for image quality, images will be recorded in NEF (RAW), JPEG, or TIFF formats (the options available vary with the model of camera). Compressed. High-end cameras also support uncom-pressed NEF/RAW.

Which image format is best in Canon?

If you want the maximum image quality, shoot at maximum resolution with low JPEG/HEIF compression (best quality, large files), or preferably in RAW format.
