About Audio Converter
Last updated: May 2026
OptiPix Audio Converter 可以在您的浏览器中直接将音频文件在所有主要格式之间进行转换。将 MP3、WAV、OGG、FLAC、AAC/M4A、WMA、AIFF、WebM、OPUS 和 AMR 文件转换为您想要的输出格式。控制比特率（64-320 kbps）、采样率（22050-48000 Hz）和声道（单声道/立体声）。一次批量转换多个文件。使用 FFmpeg.wasm 进行专业级编码，除了目标格式的特性外，不会造成任何质量损失。在转换前显示预估输出文件大小。所有处理都在本地进行 - 您的音频文件永远不会离开您的设备。
How It Works
转换器使用 FFmpeg.wasm 来解码您的输入音频，并使用您指定的比特率、采样率和声道设置将其重新编码为目标格式。所有处理都在您的浏览器本地运行。
