Free online MOV to FLAC converter

What MOV is

MOV is a multimedia container developed by Apple for QuickTime. It can hold video, audio, subtitles, timecode, metadata, and multiple streams; the .mov extension does not identify the audio codec or its quality.

QuickTime Player, iPhone and iPad cameras, macOS applications, video editors, and screen-recording software commonly create MOV files. The format is used for camera footage, screen captures, interviews, lectures, music performances, and other recordings that may later need audio extraction.

What FLAC is

FLAC, or Free Lossless Audio Codec, compresses PCM audio without discarding information and stores audio only. It supports metadata such as artist, album, title, and embedded cover art.

FLAC is useful for music archiving and editing workflows that support lossless compressed audio. Files are usually smaller than equivalent WAV files, although the reduction depends on the audio. FLAC support is less consistent than WAV support in older players, portable devices, and some editing applications.

How to convert on 101convert.com

You can convert the file for free on 101convert.com without installing software:

1. Open the MOV-to-FLAC converter on 101convert.com.
2. Select the .mov file from your device.
3. Start the conversion and wait for the output to be generated.
4. Download the .flac file, then check its duration, channel layout, and playback.

Do not upload confidential recordings unless the service's current privacy and retention terms are suitable for the file.

How to convert with FFmpeg

FFmpeg is the most controllable desktop option on Windows, macOS, and Linux. Install FFmpeg, open a terminal in the folder containing the source file, and run:

ffmpeg -i "input.mov" -map 0:a:0 -vn -c:a flac "output.flac"

• -i "input.mov" specifies the source file.
• -map 0:a:0 selects the first audio stream.
• -vn excludes video from the output.
• -c:a flac selects the FLAC encoder.
• "output.flac" specifies the destination filename.

Inspect the streams first when the MOV contains multiple audio tracks:

ffprobe "input.mov"

Use -map 0:a:1 for the second audio stream, or repeat the command with different output names to create separate FLAC files. FFmpeg's FLAC encoding is lossless by default. Optional compression levels from 0 through 12 trade encoding speed for file size:

ffmpeg -i "input.mov" -map 0:a:0 -vn -c:a flac -compression_level 5 "output.flac"

How to edit before exporting

Audacity can import a MOV when its FFmpeg import support is installed, allowing you to trim, normalize, or process the audio before choosing File → Export Audio and selecting FLAC. Exporting through an editor can change the sample rate, bit depth, channel count, or processing, so use FFmpeg or 101convert.com when extraction without editing is required.

Quality and compatibility limits

FLAC preserves the audio supplied to its encoder; it does not improve a recording. If the MOV contains AAC, MP3, or another lossy track, the FLAC is lossless only relative to the decoded lossy audio and will be larger than the original compressed track. It cannot recover discarded frequencies or detail.

With a PCM source, FLAC can preserve the source samples. Avoid unnecessary resampling or bit-depth conversion. If explicit output settings are required, use options such as -ar 48000 for 48 kHz and -sample_fmt s16 for 16-bit audio, but these settings can resample or reduce the source:

ffmpeg -i "input.mov" -map 0:a:0 -vn -c:a flac -ar 48000 -sample_fmt s16 "output.flac"

A MOV may contain no audio stream, an unsupported codec, or several language and channel tracks. Verify the selected stream, duration, sample rate, bit depth, channel count, and language after conversion. Choose WAV instead when the target application or device does not support FLAC.
