SEQ to WEBP Conversion: FAQ

What are SEQ files?

The SEQ format is associated with bitmap images created on Atari ST computers. Such devices were very popular during the 1980s and 1990s, being one of the first types of computers to gain a wide audience among home users. Similar formats include PIC and PAC. SEQ files are currently considered old and obsolete, so opening them is probably difficult.

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.
