About AIFF conversion
AIFF is useful for uncompressed editing copies, archive workflows, and projects that prefer AIFF over WAV.
AIFF output is written as uncompressed PCM audio. The output can be large, especially for long files.
The converter runs in your browser. It accepts common audio extensions such as MP3, WAV, WMA, OGG, M4R, 3GPP, OPUS, M4A, AAC, AMR, FLAC, AIFF, and APE, but actual decoding depends on browser support. Older formats such as WMA, AMR, 3GPP, APE, and exact AAC/MP4 outputs may require server-side conversion.
