AIFF file (AIFF) stores data in the AIFF format. Windows Media Audio (WMA) 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. The result is a standard WMA file readable by any compatible application. 1converter handles AIFF-to-WMA conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
