"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

STS to WEBPLL 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 WEBPLL files?

WebPLL is the lossless version of WebP, an image format released by Google in 2010 with the declared objective of improving browsing times.
