围绕您的上传框构建

与上面的转换器相同的布局语言：宽松的字体、清晰的步骤，没有一堆小灰色文本。

上传

拖放文件或浏览——与主上传器相同的功能。进度保持可见，因此交接感觉可靠。
选择格式

搜索或点击一个流行的输出。列表与您在工具中发送的内容匹配——一个视觉系统从头到尾。
下载

处理完成后，成功屏幕会显示格式并指向一个明显的下载操作。

传输中的HTTPS 服务器端处理 163+ 个输出

文件与信任

传输使用TLS。处理在我们的基础设施上运行——请查看我们的隐私页面上的保留和隐私。

一个界面用于多个工具

PDF、图像、Office文件、媒体——与工具网格相同的节奏。更少的UI模式意味着更快的理解。

常见问题

关于账户、我们如何处理文件、限制以及在工作或课堂上使用MyConvert的直接答案。

我需要一个账户吗？

不。首页上的每个工具都可以在不登录的情况下使用。如果您创建一个免费账户，您将获得一个包含转换历史和账户设置的仪表板——在您经常回来时很有用，但不是必需的。

我的文件存在哪里？

上传通过HTTPS进行，并在我们的服务器上处理——不仅仅是在您的设备上。我们仅保留输出足够长的时间以供您下载；旧文件会根据计划自动删除。文件可能被存储的时间、我们记录的内容以及您的权利在我们的隐私政策中列出。

文件大小有限制吗？

是的。每个工具页面显示其自己的限制（例如，许多图像或PDF流程允许每个文件约20–50 MB）。主页的拖放区域接受常见类型，最大为50 MB。如果文件更大，请拆分或使用桌面软件。

在工作或学校使用可以吗？

可以用于日常任务——提交、内部草稿、快速格式更改或共享非敏感材料。如果您处理受监管的数据（健康、财务、法律机密等），请在上传之前阅读我们的隐私政策和使用条款，并遵循您组织的IT和合规规则。
