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.

How to use

How to convert audio to AIFF

  1. Upload your audio file. Choose an audio file from your device or drag it into the upload area.
  2. Wait for local decoding. The browser reads the audio file and prepares it for conversion when the format is supported.
  3. Create the AIFF output. The page is already set to AIFF, so you only need to click the create button.
  4. Download manually. When the output is ready, click the download button yourself. The file does not auto-download.

Input and output format notes

These are the input extensions accepted by the upload field. Browser support is different from full codec support, so a file can be accepted by the picker but still fail if the browser cannot decode it.

Browser-created outputs are available for MP3, WAV, AIFF, OGG/OPUS when browser-supported, M4A/AAC/M4R only when native AAC/MP4 recording is supported. This deploy-safe build does not include FFmpeg WASM, CDN loading, or API conversion, so unsupported codecs are shown as unavailable instead of failing deployment.
