FAQ

Is FLAC really lossless compared to MP3 or AAC?

Yes, FLAC is truly lossless. Unlike MP3 or AAC which use lossy compression that permanently discards audio data to reduce file size, FLAC uses lossless compression that preserves every bit of audio information. The audio you download is bit-for-bit identical to the source track, meaning you get the exact same quality as the original MP4's audio stream. This makes FLAC perfect for archiving, music production, and audiophile listening where quality is paramount.

What sample rates and bit depths are supported?

Our converter preserves the original audio quality from your MP4 file, supporting sample rates up to 192 kHz and bit depths of 16-bit or 24-bit. This ensures high-resolution audio is maintained throughout the conversion process. If you need to reduce file size or compatibility requirements, you can down-sample the sample rate in the advanced settings before conversion. The tool automatically detects and preserves the source audio specifications for optimal quality.

Can I keep album art or metadata?

Album artwork from the MP4 file is not automatically embedded in the FLAC output, but you can easily add it later using any FLAC metadata editor. Popular tools like Mp3tag, MusicBrainz Picard, or Foobar2000 allow you to add album art, artist names, track titles, genres, and other metadata tags to your FLAC files. This gives you full control over organizing and tagging your music library after conversion.

Is there a maximum upload size?

Yes, files up to 2 GB are accepted for conversion. Larger video files will take more time to process but follow the same secure, browser-based workflow. The conversion time depends on the file size, video resolution, and audio complexity. All files are processed securely in your browser using encrypted connections, ensuring your media remains private throughout the conversion process.

Will the converter split multi-channel audio?

No, the converter preserves the original channel layout exactly as it appears in the source MP4 file. Whether your video has stereo (2-channel), 5.1 surround sound, 7.1, or any other multi-channel audio configuration, it will be exported directly into the FLAC file without down-mixing or channel reduction. This ensures you maintain the full audio experience and spatial information for professional audio work or home theater systems.

How is my privacy protected?

Your privacy and security are our top priorities. All file uploads travel over encrypted HTTPS connections to protect your data during transmission. Files are processed securely in your browser and are automatically deleted from our servers within minutes after conversion completion. We never store, share, or access your media files beyond the conversion process, ensuring complete privacy and security for all your audio content. Your files remain yours alone.
