What to know before converting audio to MP3
A audio to MP3 converter changes your audio file into a MP3 file for compatibility, playback, editing, sharing, or publishing. The conversion can make the file easier to use, but it cannot add quality that was not present in the source.
支持的上传格式
Audio uploads: MP3, AAC, FLAC, OGG, WMA, AIFF, WAV, and M4A files up to 200 MB.
输出
This page starts with MP3 selected, so you can convert without changing the format.
质量规则
转换会改变格式和兼容性，但无法恢复原始文件中缺失的质量、分辨率或音频细节。
| 选择 | 最适合 | 注意 |
|---|---|---|
| MP3 | Audio-only playback, podcast drafts, lectures, interviews, and notes. | The output uses the video's audio track; video quality is irrelevant. |
| WAV | Editing or cleanup after extracting audio from video. | WAV is larger and does not improve a compressed source. |
| M4A / AAC | Apple devices, mobile recordings, and compact speech files. | Useful when MP3 is not required by the destination. |
