"Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster."

What are SFF files?

SFF (Structured Fax Format) is an extension attached to digital copies of documents sent or received by fax. Such files contain raster images and data regarding page formatting. The SFF format is used by the COMMON-ISDN-API (CAPI) association which establishes standards for using ISDN equipment.

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.

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.
