MOV to AIFF Converter

How to Convert MOV to AIFF Online

1. Upload Your MOV File: Drag and drop or click "Choose Files" to add a QuickTime MOV recording — iPhone capture, ProRes export, screen recording, or third-party MOV. Only .mov is accepted; batch is supported.
2. Pick Audio Channel and Sample Rate: Default is Original (matches the MOV's embedded audio track). Set Audio Channel to Stereo for music or interview audio, or Mono to halve file size for voice-only sources. Set Audio Sample Rate to 44100 Hz for CD-compatible delivery, 48000 Hz to stay aligned with video timelines, or 8000–24000 Hz for low-bandwidth speech.
3. Trim (Optional): Switch Trim from Unchanged, then enter Start Time and Duration in seconds or HH:MM:SS.sss. Extract a single phrase, song segment, or sound bite without re-encoding the whole video.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no quality loss on the audio track.

Why Convert MOV to AIFF?

MOV is Apple's QuickTime container, used by every iPhone since 2007 and by Final Cut Pro, ProRes workflows, and macOS screen recordings. Inside, the audio is usually AAC (lossy, ~128–256 kbps from iPhone capture) or PCM (uncompressed, in ProRes masters). AIFF is the matching uncompressed sibling on the audio side: Apple defined it in 1988 on top of Electronic Arts' IFF container, and the audio data is stored as big-endian linear PCM — the same samples your DAW reads natively on macOS without any decode step.

• Logic Pro and GarageBand drop-in audio — both DAWs load AIFF instantly with full waveform display and no transcode pass, which is faster than importing a MOV and waiting for QuickTime to demux.
• Pro Tools sessions — Avid's BWF/AIFF preference on macOS means engineers can drag the AIFF straight onto a track without the "import audio from video" dialog.
• CD mastering on macOS — Apple's Music app, Burn, and Toast all accept 44.1 kHz 16-bit stereo AIFF as Red Book source material.
• Lossless archival of interview or performance audio — pulling AIFF out of a MOV preserves whatever quality was captured (AAC source stays AAC-quality but in an uncompressed container; PCM source stays bit-perfect).
• Audio-only podcast cuts from video shoots — extract the host's stereo track from a multi-cam MOV and hand it to a podcast editor without sending a 4 GB video file.
• Sample library prep — slicing field recordings or Foley out of MOV captures into AIFF lets samplers like Kontakt, Logic's Sampler, and MPC software import directly.

Frequently Asked Questions

Will the AIFF actually sound better than the AAC inside the MOV?

No. AIFF is an uncompressed container, not a quality upscaler. If the source MOV holds AAC at 256 kbps (typical iPhone recording), the AIFF will hold the AAC-decoded samples as PCM — same audible quality, much larger file. AIFF only delivers true lossless quality when the MOV's audio track was already PCM (most ProRes masters, some screen recordings). Where AIFF wins regardless of source is workflow: no re-decode in your DAW, no further generation loss, and stable metadata.

Why is my AIFF so much larger than the original MOV?

Because the MOV stored audio compressed (usually AAC at 128–256 kbps for iPhone capture, ~1–2 MB per minute) and AIFF stores it uncompressed at ~10 MB per minute for 44.1 kHz 16-bit stereo. The video portion you discarded is gone, but the audio expands roughly 5–8x. To shrink the output, lower Audio Sample Rate, switch Audio Channel to Mono if source is mono, or extract only the part you need via Trim.

What's the difference between AIFF and AIF? And AIFC?

.aiff and .aif are the same format — Audio Interchange File Format, just a 4-character vs 3-character extension. Either plays identically in every DAW. AIFC (.aifc) is Apple's compressed AIFF variant from 1991 that supports codecs like µ-law, A-law, and IMA ADPCM inside the AIFF container; it's rarely used today. For the reverse direction see AIFF to AIF or AIFF to AIFC.

Why is bit depth not exposed as an option?

The output is fixed at PCM 16-bit big-endian (PCM_S16BE), which matches CD-standard AIFF and the default that Logic, Pro Tools, and GarageBand assume. If your source MOV was 24-bit PCM (rare; ProRes masters or pro field recorders), the converter resamples to 16-bit; the resulting file is half the size of 24-bit AIFF with no audible difference for most material. If you need 24-bit for further mastering work, convert to WAV instead, which supports more bit depths.

Does AIFF play on Windows and Android?

AIFF plays on Windows via VLC, foobar2000, Audacity, Reaper, and most DAWs — Windows Media Player and the Films & TV app do not handle AIFF natively. Android playback is patchy: VLC for Android and Poweramp open AIFF, the stock Files/Music apps usually don't. For cross-platform sharing, MOV to WAV is usually a safer choice because WAV is the Windows-native uncompressed format with broader OS support, while keeping identical audio quality to AIFF.

Can I extract just one section without re-encoding the whole video?

Yes — set Trim to "Trim" and enter Start Time and Duration. Only that segment is read from the MOV and written to the AIFF, which saves processing time and output size. For longer or more precise editing (multiple regions, fade-ins), grab the whole audio track first, then use Audio Cutter or Trim AIFF on the resulting file.

My MOV is from iPhone screen recording — what audio is inside?

iOS screen recordings store stereo AAC at 44.1 kHz with bit rate around 128–192 kbps; system audio and microphone (if enabled) are pre-mixed into that single AAC track. Converting to AIFF gives you 44.1 kHz 16-bit stereo PCM (~10 MB/min) that any editor can re-mix or denoise without re-decoding AAC each pass.

Do you store my file after conversion?

No. Conversion runs in your browser session and the file is removed from temporary storage shortly after you download it. There's no account, no watermark, and no recompression of the audio track beyond the format change you requested. For batch jobs, you can queue several MOVs at once and download each AIFF individually.

What if I need MP3 or FLAC instead?

Pick the destination that matches your delivery target. MOV to MP3 for podcast distribution and broadest device support. MOV to FLAC for lossless compression at roughly half the AIFF size — same quality, smaller files, but no native Apple Music/Logic integration without import.
