MPEG-4 Part 14 (MP4) is a container video format used for streaming, phone video, web delivery and editing exchange. Files saved as MP4 usually come from MPEG / ISO. Before converting, check that the source is the highest-quality copy you have, because every later step can only preserve what is already there.
The target is Audio Interchange File Format (AIFF), a uncompressed audio format chosen for apple production workflows. The video track is discarded and only the audio stream is decoded, re-encoded and packaged in the target container. The output keeps the original dimensions or sample rate unless you change them, so this step changes the encoding rather than the content.
AIFF writes big-endian PCM, the Apple studio equivalent of WAV. Files are large, yet Pro Tools and Logic import them without conversion. Only the audio stream is decoded; video tracks, chapter markers and subtitles in the source are dropped from the output. Expect a smaller output file, which is usually the reason to pick AIFF.
This conversion runs locally in your browser tab through Canvas or FFmpeg.wasm. The file is read from your device, decoded, re-encoded and handed back as a download; it is not uploaded to a conversion server. That keeps private recordings, client material and unreleased artwork off shared infrastructure.
After the download, play or open the result before deleting the original. Check the first and last seconds, confirm that transparency, rotation metadata or sample rate survived, and compare file sizes. If something looks wrong, retry with a higher quality setting rather than converting the output again.

How it works
- 01
Open the MP4 to MP3 Converter workspace and drop the MP4 file, or click the drop zone to browse. Local processing needs no account.
- 02
Select AIFF as the output format and set the quality or width control to match the destination platform.
- 03
Start the job and leave the tab open while the local encoder runs; the progress log reports each stage.
- 04
Download the result, verify it, then keep the original until the destination accepts the new file.

Frequently asked questions
Is MPEG-4 Part 14 to Audio Interchange File Format conversion free?
Yes. Single-file MP4 to AIFF conversion is a Tier 1 local tool, free without an account and without a daily quota. Pro only matters for batch workflows and cloud jobs.
Are my files uploaded to a server?
No. The MP4 file is decoded in this browser tab and the AIFF output is created in memory. Nothing is sent to AIMP6 storage, and closing the tab removes the working data.
Will converting MPEG-4 Part 14 to Audio Interchange File Format reduce quality?
The video track is discarded and only the audio stream is decoded, re-encoded and packaged in the target container. If the result must stay archival, keep the original file and treat the converted copy as a delivery version.
Can I convert several MP4 files at once?
The image workspace accepts multiple files up to the browser memory limit; audio and video jobs run one file at a time because FFmpeg.wasm holds the whole stream in memory. Batch cloud processing is a Pro workflow.
Which tool handles MPEG-4 Part 14 to Audio Interchange File Format?
The MP4 to MP3 Converter workspace is the canonical page for this pair. It accepts MP4 input and writes AIFF, and the same page exposes format notes, FAQs and related conversions.
