M2TS is a document format: it stores data in the M2TS format. WMA is a audio format that encodes audio with Microsoft's proprietary WMA codec, primarily found in files created by Windows Media Player. This conversion changes the file's encoding, compression method, and supported feature set. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. Converting between these two formats is common when the source application does not support WMA natively or when the target platform only accepts WMA. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
