PDF 转 JPG
将 PDF 的每一页转换为独立的 JPG 图片。
使用方法
上传一个 PDF，每一页都会渲染为独立的 JPG 图片，可单独下载，也可打包为 ZIP 一起下载。
JPG 图片的分辨率是多少？
页面渲染分辨率约为 288 DPI——足够清晰，可用于打印或放大查看，不是低分辨率缩略图。
我可以只转换特定页面，而不是整个 PDF 吗？
每一页都会转换为单独的 JPG，但您可以选择要保留哪些——只下载您需要的页面。
Can I convert a password-protected PDF?
Not directly — you'll need to remove the password first using a PDF reader that supports it, then convert the unlocked file.
Does this work on mobile?
Yes — it runs in any modern mobile browser on iOS or Android, no app install needed.
Will the JPGs be numbered in page order?
Yes — each image is named to match its page number, so they stay in order when downloaded or zipped.
Is my PDF uploaded anywhere to convert it?
No — the conversion runs entirely in your browser using pdf.js. Your PDF and the JPGs it produces never leave your device or touch a server.
Can I get PNG instead of JPG?
No — output here is JPG only. It keeps files small and works everywhere, which covers most conversions. If you specifically need lossless PNG, this isn't the tool for it.
Does this extract the images inside my PDF, or convert whole pages?

Can I choose the JPG quality or make smaller files?
Not right now — every page renders at a fixed high quality (about 288 DPI), so there's no slider to trade quality for a smaller file. It means you don't have to guess at settings, but you also can't dial it down if you want tinier files.
How do I turn the JPGs back into a PDF?
