MEF to WEBP Conversion: FAQ

What are MEF files?

MEF is the proprietary RAW image format of Mamiya cameras. This high-end Japanese brand is well known among professional photographers for producing photographic equipment and has a history dating back to the 1940s. Also known as "digital negatives", RAW images represent uncompressed images which need to be customized using an editing program. They are often favoured by professional photographers for offering high-quality images including a large amount of details, which can be highly suitable for printing.

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
