Format Details
AIFF
AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple, commonly used in professional music production and macOS workflows. Convert to MP3, WAV, FLAC, and other formats.
audioWMA
WMA (Windows Media Audio) is a series of audio codecs and their corresponding audio coding formats developed by Microsoft. It is a proprietary technology that forms part of the Windows Media framework. WMA consists of four distinct codecs: WMA, WMA Pro, WMA Lossless, and WMA Voice.
audioConverting AIFF to WMA: what actually changes
AIFF to WMA is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .AIFF and .WMA each hold
.AIFF is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. .WMA is a audio format built for listening to or editing a recording, storing sample rate, channels and bitrate. Converting between them is a decision about which of those two jobs the result needs to do.
What changes in the conversion
Both files belong to the audio category, so this is a like-for-like repackage: the same kind of content, stored in a different container. What changes is how .WMA encodes sample rate, channels and bitrate — not what the file is about.
Quality and file size
.AIFF keeps every detail, but .WMA uses lossy compression to stay small. The first conversion is where quality is decided — after that, re-saving the .WMA again compresses it a second time. Keep your original file if you may need to re-export later.
When this conversion is the right one
Reach for .WMA when the software, device or platform you are sending to expects it — the content is the same audio, only the packaging differs. The reverse direction works the same way, so you can always convert back from .WMA to .AIFF using the same tool.
Tips for a clean AIFF to WMA conversion
Start from the original file
Convert the .AIFF you started with, not an earlier .WMA output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Audio/aiff becomes audio/x-ms-wma. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Length decides the time
Conversion runs in real terms on duration: a few seconds of media finishes almost at once, while a full-length .AIFF takes noticeably longer. Upload once and let it finish rather than retrying.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge audio files, split or compress the source first.
