Supported formats and quality options

We offer a range of formats to suit different devices and use cases. Here's a quick overview of what you can choose from when using the YouTube downloader:

Video formats

• MP4 – H.264/AVC or H.265/HEVC, commonly 1080p, 720p, 480p, and sometimes 4K depending on source video.
• WEBM – VP9 or AV1 codecs, a good choice for web playback and compatibility with some browsers and devices.
• MKV – occasionally offered for high-fidelity keeps; depends on video source.

Audio formats

• MP3 – widely supported, very portable for offline listening. Bitrate options typically include 128 kbps, 192 kbps, and 320 kbps.
• AAC – efficient, good quality at lower bitrates.
• OGG – a free and open format useful for certain devices.

Quality options explained

Quality and file size scale with bitrate and resolution. For video, higher resolutions (1080p, 4K) deliver crisper images but yield larger files. For audio, higher bitrates (192 kbps, 320 kbps) provide richer sound with larger file sizes. You can always opt for a smaller file if you're conserving space or streaming offline on mobile networks.

Use cases — why you'd choose this format

Understanding practical use cases helps you pick the right option for your needs. Here are common scenarios for choosing MP3, MP4, or other formats from our YouTube downloader:

• Offline listening on mobile: MP3 at 128 kbps–320 kbps delivers good quality without large files.
• Offline video viewing on a tablet: MP4 at 720p–1080p is ideal for a balance of quality and size.
• Creating a playlist or podcast: MP3 with 192 kbps–320 kbps provides clear sound for speech and music.
• Educational clips or lectures: High-bitrate MP4 preserves details in on-screen text and visuals.

Reliability, safety, and copyright considerations

We respect copyright law and YouTube's terms of service. The YouTube downloader is intended for personal, non-commercial use where you have the right to download the video or audio.

We do not store personal data beyond what is needed to process your request, and we do not require registration or login to use the core features of the service.

Comparison with other formats

Sometimes you may wonder whether MP3 should be used instead of AAC, or MP4 instead of WEBM. Here's a quick comparison to help you decide:

• AAC often provides better quality at lower bitrates than MP3, but MP3 remains exceptionally universal. Choose AAC for smaller files with similar or better perceived quality where supported by your player.
• MP4 with H.264/AAC is more universally supported, while WEBM (VP9/AV1) can offer better efficiency in modern browsers and devices. If you need broad compatibility, MP4 is usually safer.
• If you only need audio, MP3/AAC gives significantly smaller files with minimal performance impact. For video content or presentations, MP4 provides the full experience.
