Do I need QuickTime or any Apple software to convert MOV to MP3?

No. Zolkit reads MOV files natively in the browser using FFmpeg WebAssembly. You do not need QuickTime, iTunes, iMovie, macOS, or any Apple software. MOV conversion works on Windows, Linux, Android, and any device with a modern browser.

Why is my MOV file so large?

iPhone MOV files contain HEVC (H.265) or H.264 video at up to 4K resolution, which can be 400–700 MB per minute. The audio track itself is usually under 5 MB per minute as AAC. MP3 conversion extracts only the audio, reducing a 500 MB MOV to a 3–5 MB MP3.

Can I convert iPhone Cinematic Mode videos?

Yes. Cinematic Mode videos are standard MOV files — the depth/focus metadata is in a separate track that Zolkit ignores. The audio track is extracted normally.

Will this work for screen recordings from a Mac?

Yes. macOS screen recordings are saved as MOV files. The audio (microphone, system audio, or both) is extracted exactly as recorded.

Bitrate

MOV is Apple's video container format, used by iPhone, iPad, and macOS screen recordings. Every iPhone video is saved as a MOV file containing HEVC or H.264 video and AAC audio. Converting MOV to MP3 is a common task when you want to extract a voice memo shot as a video, save a FaceTime-quality audio recording, or pull music from a video clip you recorded. Zolkit handles MOV files natively — no conversion app needed. The browser reads the MOV container, identifies the AAC audio track, and re-encodes it to MP3 at your chosen bitrate. iPhone audio is typically recorded at 44.1 kHz stereo, which converts cleanly to MP3. At High quality (320 kbps), the resulting MP3 is bit-for-bit equivalent in perceived quality to the iPhone's original AAC audio. A 1-minute iPhone video at 4K/30fps produces roughly a 2–3 MB MP3 file at standard quality — small enough to send via iMessage or email without compression.
