实用细节

放入文件之前。

Are my files uploaded?

The tools available now run in your browser, and the contents of your files are not uploaded to our conversion service. Audio, video and advanced document tools would need server processing; they are planned, shown as not available yet, and cannot be used at present.

任何文件都能转换成其他任意格式吗？

No. Only supported pairs are offered, and the pairs marked as not available yet cannot be used today. When available, MP3 to MP4 will create a static-background video using your audio, PDF to Word will extract editable text without preserving original fonts, images or complex layouts, and PDF to Excel will extract structured tables, not entire page designs.

免费吗？

Yes. The free allowance is five successful conversions a day, resetting at 00:00 UTC, and you do not need to sign in. A conversion only counts when it succeeds, and downloading a result again does not count again.

转换会提升质量吗？

更改格式无法找回之前已丢失的细节。重新编码音频、视频或 JPG 文件可能降低质量。请保留原文件，并在使用前检查转换结果。
