About WMA to SMP Conversion
Short answer: yes, you can convert WMA to SMP online for free, and quality is well preserved with the right settings. Just upload your .wma file to CocoConvert, pick SMP as the output, and click Convert. The whole process takes seconds.
Now for the details. WMA (Windows Media Audio) is Microsoft's audio codec — less common today but still found in legacy collections. SMP is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your WMA file is decoded and re-encoded as SMP. Converting WMA to SMP 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.
