MP3 to WAV — 常见问题
Why is the WAV so much bigger?+
WAV is uncompressed PCM — roughly 10× an MP3. That's expected: it's the trade-off for a lossless, editing-friendly file.
Does converting to WAV improve quality?+
No. It can't restore detail the MP3 already discarded — but it won't lose any more, which is useful before further editing.
Is it uploaded?+
No — the MP3 is decoded and the WAV is written entirely in your browser.
What sample rate is the WAV?+
The same sample rate as the source MP3, as 16-bit PCM.
你们会把我的文件上传到服务器吗？+
不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。
有文件大小限制吗？+
我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
