About FTS to WEBP Conversion
Short answer: yes, you can convert FTS to WEBP online for free, and quality is well preserved with the right settings. Just upload your .fts file to CocoConvert, pick WEBP as the output, and click Convert. The whole process takes seconds.
Now for the details. FTS 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 FTS file is decoded and re-encoded as WEBP. Converting FTS 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.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.
