This tool supports all common video formats including MP4, MOV, AVI, MKV, WebM, FLV, WMV, and more. FFmpeg automatically detects the video format and extracts the audio stream regardless of the container format.

AAC offers better audio quality than MP3 at the same bitrate and file size. It's the preferred format for Apple devices (iPhone, iPad, Mac), podcasts, and streaming services. AAC at 256kbps delivers quality comparable to MP3 at 320kbps.

For speech-focused content like podcasts, 'Good' (192kbps) or 'Smaller' (128kbps) provides excellent clarity while keeping file sizes manageable. For music content, choose 'High' (256kbps) for best quality.

The output quality depends on both the source video's audio and your selected bitrate. If the video has high-quality audio, choose 'Best' or 'High'. Converting from lower-quality video won't improve audio—the output quality is limited by the source.

Common uses include creating podcasts from video content, making music playlists from concert videos, extracting interviews or lectures for audio-only listening, reducing file sizes for mobile devices, and preparing audio for editing or remixing.

Extraction speed depends on video length and your device. A typical 5-minute video processes in 10-30 seconds on modern computers. Longer videos or mobile devices may take proportionally longer, but processing happens entirely in your browser.

Yes! Despite being Apple's preferred format, AAC is universally supported on Android phones, Windows computers, most car stereos, and nearly all modern audio players. Only very old devices might lack AAC support.

Currently, this tool processes one video at a time for optimal browser performance. For multiple files, process them sequentially. Each extraction uses your selected quality settings.

AAC is the audio codec (compression method), while M4A is the file container format. M4A files contain AAC audio. Our tool outputs .m4a files with AAC audio, which is the standard format used by iTunes, Apple Music, and most podcast platforms.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your video files never leave your device, ensuring complete privacy. No server uploads, no cloud processing.
