ERF to WEBP Conversion: FAQ

What are ERF files?

ERF is the proprietary RAW image format for Epson cameras. An ERF file contains an uncompressed image which can be processed using an advanced image editing software and can be printed using an Epson printer. Many professional photographers prefer to shoot in RAW mode because this allows a better control over the creative editing of the image, and more freedom to customize and transform the image using aspects such as color correction and white balance before converting to a more popular format.

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.
