常见问题解答
音频转换器是免费的吗?
Yes. Convertr lets you convert files online for free. There are no fees, subscriptions, limits on download count, or watermark overlays.
哪些常规的<unk>子会得到支持?
We support six standard presets: 64 kbps, 96 kbps, 128 kbps, 192 kbps, 256 kbps, and 320 kbps. Bitrate changes happen solely because you select them.
提高音频质量?
No. Re-encoding compressed audio (e.g. upsampling a 128 kbps MP3 to 320 kbps) cannot restore lost detail. It only makes the file larger without any improvements.
