Short answer: yes, you can convert G3 to WEBP online for free, and quality is well preserved with the right settings. Just upload your .g3 file to CocoConvert, pick WEBP as the output, and click Convert. The whole process takes seconds.
Now for the details. G3 is a widely used file format. WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. Converting between these two formats lets you convert between formats quickly.
Your G3 file is decoded and re-encoded as WEBP. Converting G3 to WEBP maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
