STS to WEBP Conversion: FAQ

What are STS files?

An STS file contains a two-dimensional vector representation of the bottom solder mask which makes up a printed circuit board (PCB), and it is most likely created and processed with Eagle software. STS is part of a larger family of extensions called Gerber, which represent the de facto standard used in the PCB industry. Gerber files describe various aspects of electronic boards, including copper layers, solder masks, electrical connections, drilling or milling data. Similar formats include SOL, STC and PLC.

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.
