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..
