如何使用「PDF 转 PPT」？How do I use the PDF to PowerPoint Converter tool?
在「PDF 转 PPT」中，按需设置「清晰度」、「页码（留空为全部）」等选项，然后点击「转换为 PPT」按钮即可。支持拖放文件。加密的 PDF 选好后会先出现「打开密码」栏和「打开」按钮，输入密码点「打开」后再继续。In the PDF to PowerPoint Converter: Set "Quality", "Pages (empty = all)", then click "Convert to PPT". Drag-and-drop files is supported. For an encrypted PDF, a Password field and an Open button appear after you choose it — enter the password and click Open first.
转换后的幻灯片能编辑文字吗？Can I edit the text on the slides?
不能直接编辑：每页以高清图片放在幻灯片上，保证和 PDF 外观完全一致；页面上的文字会写进演讲者备注，可以复制出来重新排版。Not directly: each page is placed as a high-resolution image so it looks exactly like the PDF. The page text is written into the speaker notes so you can copy it and rebuild slides.
幻灯片比例是怎么定的？How is the slide size chosen?
按第一页 PDF 的宽高设置幻灯片尺寸（例如 16:9 的 PDF 得到 16:9 幻灯片，A4 得到竖版），其余尺寸不同的页面会等比缩放居中。The slide size follows the first page (a 16:9 PDF gives 16:9 slides, A4 gives portrait slides); pages with other sizes are scaled to fit and centred.
文件会很大吗？Will the file be large?
每页是一张 JPEG 图片，150 DPI 下通常每页 100–400 KB；选择 96 DPI 可以减小体积，200 DPI 投影更清晰。Each page is a JPEG; at 150 DPI typically 100–400 KB per page. Choose 96 DPI for smaller files or 200 DPI for sharper projection.
加密的 PDF 可以处理吗？Can it handle password-protected PDFs?
可以。如果 PDF 需要打开密码，会提示你输入；只有权限限制（无打开密码）的文件会自动打开。输出文件不再带密码，如需加密请使用“PDF 加密”工具。Yes. If the PDF needs an open password you'll be asked for it; files with only permission restrictions open automatically. The output is not password-protected — use the Protect PDF tool if needed.
文件会上传到服务器吗？Are my files uploaded?
不会。PDF 在你的浏览器里用 pdf-lib / pdf.js 处理，文件不会离开你的设备，关闭页面后不留存任何数据。No. The PDF is processed in your browser with pdf-lib / pdf.js; files never leave your device and nothing is kept after you close the page.
