How to Convert Video to AIFF Online
- Upload Your Video File: Drag and drop or click "+ Add Files" to import MP4, MOV, MKV, AVI, WebM, MTS, AVCHD, FLV, WMV, 3GP, or any of 35+ supported video containers. Batch uploads are supported — every file gets the same output settings.
- Pick Audio Channel and Sample Rate: Default is "Original" (preserves the source track as-is). Switch Audio Channel to Stereo for music or Mono for voiceover and dialogue. Set Audio Sample Rate to 44100 Hz for CD-standard masters, 48000 Hz for video and broadcast deliverables, or up to 192000 Hz for high-resolution archival. AIFF stores uncompressed big-endian PCM, so these two choices fully determine fidelity and file size.
- Trim (Optional): Use the Trim control to set a start time and duration in HH:MM:SS.ms — useful for grabbing one song from a concert recording or a single line of dialogue from a longer take. Leave Unchanged to export the full track.
- Convert and Download: Click "Convert" and download your
.aifffile. Processing runs through your session — no sign-up, no watermark, files auto-purge after a short retention window.
Why Convert Video to AIFF?
AIFF (Audio Interchange File Format) was released by Apple on January 21, 1988 and remains the native uncompressed audio format across the Apple pro-audio stack — Logic Pro, GarageBand, Final Cut Pro, and Pro Tools on macOS all read and write .aiff without conversion. Pulling the audio out of a video into AIFF gives you a lossless, edit-ready master rather than the re-encoded MP3 or AAC most "extract audio" workflows produce.
- Logic Pro / GarageBand sessions — AIFF is one of the default working formats on macOS DAWs. Drop the file straight onto a track; no transcode, no quality loss versus the source video's audio.
- Final Cut Pro and iMovie editing — When you cut a music video, podcast, or interview, Final Cut prefers AIFF or WAV for reliable scrubbing and sample-accurate edits versus the compressed audio inside an MP4 container.
- CD mastering and broadcast delivery — Red Book CD masters require 16-bit / 44.1 kHz PCM, and many broadcasters specify 24-bit / 48 kHz AIFF for stem delivery. Convert your video's audio once and feed it into either pipeline.
- Sample libraries and Foley — Field recordings shot on a camera or phone are easier to chop, loop, and time-stretch as AIFF in Ableton, Reason, or Kontakt than as compressed audio inside a video container.
- Archival masters — AIFF is lossless and well-documented; it's a safer long-term store for an interview, lecture, or live performance than re-encoding to lossy MP3 or AAC.
- Voice acting and dubbing — Studios routinely require AIFF deliverables. Pull dialogue out of a reference video and send the AIFF to the editor without quality degradation.
AIFF vs WAV vs MP3 — Format Comparison
| Property | AIFF | WAV | MP3 |
|---|---|---|---|
| Compression | Uncompressed PCM | Uncompressed PCM | Lossy (MPEG-1 Layer III) |
| Byte order | Big-endian (Motorola) | Little-endian (Intel) | N/A |
| Typical file size (3 min, 16-bit/44.1 kHz stereo) | ~30 MB | ~30 MB | ~3-7 MB |
| Max sample rate | 192 kHz+ (80-bit float field) | 192 kHz+ | 48 kHz |
| Max bit depth | 32-bit integer | 32-bit float | N/A (constant bitrate) |
| Metadata | ID3v2 + native chunks | LIST/INFO chunks | ID3v1/v2 |
| Native DAW | Logic, GarageBand, Pro Tools | Cubase, Studio One, Reaper | None (lossy) |
| Best for | Apple-stack mastering, archival | Cross-platform PCM masters | Streaming, podcasts |
Sample Rate Guide for AIFF
| Sample Rate | Use Case | Notes |
|---|---|---|
| 24000 Hz | Voice memos, low-bandwidth speech | Acceptable for dialogue only; noticeably dull on music |
| 44100 Hz | CD masters, music streaming | Red Book CD standard since 1980 |
| 48000 Hz | Film, TV, YouTube, broadcast | Default audio rate for video deliverables |
| 88200 / 96000 Hz | High-resolution audio releases | 96 kHz is the DVD-Audio / Blu-ray standard |
| 176400 / 192000 Hz | Pro mastering, archival | Use only if your source actually contains that bandwidth |
Tip: don't upsample. If the audio inside your MP4 is 48 kHz AAC, exporting to 192 kHz AIFF doesn't add detail — it just makes the file four times larger. Match the source unless a delivery spec demands otherwise.
Frequently Asked Questions
Will the conversion add quality versus the audio already in my video?
No — and that's the point. The AIFF will preserve every bit the source video's audio track contains, but it cannot reconstruct detail that the original encoder (AAC, AC-3, Opus) already discarded. AIFF acts as a lossless wrapper so further edits, EQ, and mixing don't compound compression artifacts.
Why is my AIFF roughly 10 MB per minute when the source MP4 was 2 MB per minute?
AIFF is uncompressed PCM. A stereo 16-bit/44.1 kHz file runs ~10.1 MB per minute (44100 samples/sec x 2 bytes x 2 channels x 60 sec). 24-bit/48 kHz stereo is closer to 16.5 MB per minute. The MP4 was lossy AAC — typically 128-256 kbps, or ~1-2 MB per minute. The math is correct; AIFF trades file size for a fully editable master. If you need a smaller lossless file, try Video to FLAC instead.
Should I pick AIFF or WAV?
Both store the same uncompressed PCM data. AIFF uses big-endian byte order (Motorola/Apple heritage) and is the default native format in Logic Pro, GarageBand, and Final Cut Pro. WAV is little-endian and slightly more common on Windows DAWs and as a universal interchange format. Modern DAWs on either OS read both without trouble — pick AIFF if your final workflow lives on macOS, otherwise Video to WAV is fine.
What sample rate and bit depth should I choose for Logic Pro?
For most music projects, set your Logic Pro project to 24-bit / 48 kHz and export AIFF at the same settings — that gives headroom for processing without the file-size penalty of 96 kHz. Use 16-bit / 44.1 kHz only if the destination is a Red Book CD. Use 24-bit / 96 kHz only when the source video genuinely contains that bandwidth (high-end field recorders feeding into a camera).
Can I convert AVCHD / MTS camcorder footage to AIFF?
Yes. The accepted-extensions list includes AVCHD, MTS, M2TS, MXF, and most prosumer camera containers. The audio stream inside AVCHD is typically AC-3 at 48 kHz, which decodes cleanly to AIFF at the same sample rate. Keep "Audio Sample Rate" on Original or set it to 48000 Hz to match the source.
Does it work with 4K, 8K, or HDR video?
Yes — resolution and HDR metadata are irrelevant once we strip the audio stream out. A 4K HEVC clip and a 720p H.264 clip produce identical AIFF output as long as their audio tracks are identical. File processing time is driven mostly by audio length and your upload speed, not by video resolution.
Will the converted AIFF play on Windows?
Yes. AIFF playback is built into Windows Media Player, Groove, Foobar2000, VLC, and every modern DAW. The big-endian byte order is handled transparently by the OS — you'll never notice. If a specific tool refuses AIFF, convert to WAV (same PCM data, different byte order).
Can I split a long video into multiple AIFF clips?
Use the Trim control to grab a single segment per conversion. For multi-segment splits, run the conversion several times with different start/duration values, or extract a full-length AIFF first and then use Audio Cutter to chop it into clips. Both approaches preserve the underlying PCM bit-perfectly.
Is there a file size or length limit?
Server-side processing handles typical music videos, interviews, and lectures (a 60-minute 1080p MP4 is usually under 2 GB). Very long broadcast masters or uncompressed camera files may need to be trimmed first — use the Trim option to grab the section you actually need rather than uploading hours of footage.
