FLAC is lossless audio compression — ~50% the size of WAV with mathematically identical audio. The audiophile format of choice: Tidal HiFi and Amazon Music HD stream FLAC, and vinyl-rip communities archive in it. Convert to FLAC when your destination is critical listening on capable gear, or long-term archival of source recordings.
Pulling the soundtrack out of a video means dropping every video frame and keeping only the audio stream — smaller file, listen-only content.
Files up to 10 MB on the free plan, up to 1 GB on Pro — enough for lecture recordings, music videos, podcast video versions, and screen captures. Long videos (hour-plus) need Pro because the audio track alone can push past the free ceiling.
For voice content (interviews, lectures, podcasts), 128 kbps FLAC is more than enough. For music, aim higher — 192 kbps for casual listening, 320 kbps if you want transparency to the source. The source can't go higher than it already is; if the video's audio was already 128 kbps AAC, exporting at 320 kbps just makes a bigger file.
Extraction is fast — a 30-minute video typically produces its FLAC in a few seconds. Both the video you uploaded and the extracted audio are permanently deleted from our servers within 30 minutes.
A MOV container holds separate video and audio streams. Extraction reads the audio stream, re-encodes it (or copies it, if the target codec matches) into your chosen FLAC container, and throws away the video entirely. Metadata like title and track info carry over where the format supports it.
Six scenarios where extracting audio to FLAC solves a real problem.
A recorded lecture, webinar, or class captured as MOV carries hours of good audio and a static talking head. Extracting to FLAC produces something you can listen to on a commute — much smaller, playable on any audio app.
For music videos of tracks you own, extracting the FLAC lets you add the song to your regular listening rotation without needing to keep the video around. (Do keep an eye on rights — extraction from third-party sources isn't a licence.)
Recording a video interview and then distributing the audio-only version to podcast platforms is standard practice. Extracting to FLAC gives you the podcast episode without touching the video edit.
Whisper, Otter, and every other transcription service accept audio directly. Uploading video wastes bandwidth and, in some cases, is rejected outright. Extract to FLAC first, upload, get the transcript back in a fraction of the time.
Sound effects and short clips extracted from videos become FLAC files ready to import into audio editors, DAWs, or ringtone makers. Video is unnecessary baggage for these use cases; extracting saves the round-trip.
A 1 GB MOV lecture recording carries maybe 60 MB of actual audio. If the video track is disposable — say, a talking head — extracting to FLAC cuts storage by 90% while preserving the content that matters.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

MOV (QuickTime Movie) is a multimedia container format developed by Apple in 1991 for its QuickTime media framework. It was one of the earliest container formats designed to hold video, audio, and text in a single file, and its architecture directly influenced the development of the MP4 standard. MOV remains the native video format for macOS and iOS, deeply integrated into Apple's ecosystem of creative tools including Final Cut Pro.
MOV is widely used in professional video editing workflows, particularly with Apple's Final Cut Pro, where it supports high-quality codecs like ProRes and HEVC. The format excels at preserving video quality during the editing process, making it a staple in film, television, and content production. However, MOV files tend to be larger than their MP4 equivalents, and compatibility outside the Apple ecosystem can be inconsistent — Windows and Linux users may need additional codecs or conversion to play MOV files reliably.
