FAQ

What is the difference between M4A and MP3?

M4A and MP3 are both compressed audio formats, but M4A uses more advanced codecs (AAC or ALAC) that provide better audio quality than MP3 at the same file size. M4A files typically offer superior sound fidelity, especially at lower bitrates, thanks to AAC's more efficient compression algorithm. M4A has full native support on Apple devices (iPhone, iPad, iPod, iTunes, Apple Music), while MP3 has universal compatibility across all platforms. M4A is the preferred format for iOS users and Apple ecosystem, offering better quality-to-size ratio and seamless integration with Apple services.

Can I set a specific bitrate for the M4A file?

Yes, you have full control over the bitrate settings. After uploading your MP4 file, open "Advanced settings" to choose any bitrate from 64 kbps to 320 kbps, or keep the source value for automatic quality preservation. Lower bitrates (64-128 kbps) create smaller files suitable for voice recordings, podcasts, or limited storage, while higher bitrates (192-320 kbps) provide better quality for music. The default setting balances file size and audio quality based on your source material.

Will the conversion keep chapter markers or subtitles?

No, only the audio track is extracted from the MP4 video. Chapter markers, subtitles, video tracks, and any other non-audio data are not included in the exported M4A file. M4A is a pure audio format, so it contains only the audio stream. If you need to preserve chapters or subtitles, you would need to keep the original MP4 file or use specialized audio editing software that supports chapter markers in audio-only formats.

Is there a file size limit for uploads?

Yes, you can upload videos up to 2 GB for conversion. Larger video files may take longer to process but follow the same simple, secure workflow. The conversion time depends on factors such as file size, video resolution, audio complexity, and selected bitrate. All files are processed securely using encrypted HTTPS connections, ensuring your media remains private throughout the conversion process. For very large files, consider splitting them into smaller segments or using video editing software to extract the audio portion first.

Does M4A play on Android and Windows?

Yes, M4A files play on Android and Windows, though support varies by player. Most modern media players like VLC, Windows Media Player, Groove Music, Spotify, and foobar2000 can open M4A files without requiring extra codecs. Android devices typically support M4A natively, and Windows 10/11 includes built-in M4A support. However, some older players or devices may require additional codec packs. For maximum compatibility across all platforms, MP3 remains the most universally supported format, but M4A works well on most modern systems.

How is my privacy protected?

Your privacy and security are our top priorities. All files are transferred via encrypted HTTPS connections to protect your data during transmission. Files are processed securely in volatile memory (RAM) 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, with no permanent storage or third-party access.
