常见问题
如何将PDF转换为PNG？
上传您的PDF，选择分辨率预设（标准、高分辨率或最高），选择要转换的页面，然后点击'Convert to PNG'。图片会立即开始下载。
在线将PDF转换为PNG安全吗？
非常安全。我们的转换器完全在您的浏览器中运行，使用WebAssembly技术。您的文件不会离开您的设备——即使我们想查看也无法做到。
PNG和JPG有什么区别？
PNG使用无损压缩——每个像素都被精确保留，因此文件较大。JPG使用有损压缩——文件更小，但会丢失一些细节。文字、图表和截图建议使用PNG；照片建议使用JPG。
PNG支持透明背景吗？
支持。PNG支持完整的Alpha透明度，即图片的某些部分可以是透明的。这使PNG非常适合用于需要叠加在其他内容上的Logo、图标和图形。
为什么PNG文件比JPG大？
PNG使用无损压缩，精确保留每个像素。JPG会丢弃部分视觉信息以缩小文件大小。代价是：PNG的画质完美无损，而JPG文件通常小3-5倍。
可以只转换特定页面而不是整个PDF吗？
可以。上传后，您会看到每页的缩略图预览。选择或取消选择单个页面，只转换您需要的页面。
可以在手机上将PDF转换为PNG吗？
可以。我们的转换器支持所有现代浏览器——iPhone、iPad、Android、Mac、Windows和Chromebook。无需安装任何应用。
需要安装软件或创建账户吗？
不需要。一切都在浏览器中运行，无需安装。每天可以免费转换3个PDF，无需账户。需要更多？购买$3.99日通行证即可。
