关于此 PDF 转 JPG 工具
PDF to JPG renders a page of your PDF as a picture. Choose which page you want and it is rasterized at 180 DPI - sharp enough for presentation slides, documentation, social posts and messaging apps, where a PDF attachment would be awkward or simply would not preview. This is the tool to reach for when you need to show a page rather than send a document: dropping a certificate into a slide deck, posting a menu or flyer where images display inline, or grabbing a diagram out of a report. Use the quality setting to trade file size against sharpness, and pick PDF to PNG instead when you need lossless output for text-heavy pages or further editing.

PDF to JPG vs. taking a screenshot
A screenshot captures only what fits on your display, at your screen resolution, usually with the viewer interface around it. This tool renders the full page at a fixed 180 DPI, so the result is complete, cleanly cropped to the page and consistently sharp.
That matters most when the image will be enlarged, printed or projected - a screenshot of a zoomed-out page looks soft, while a rendered page stays crisp.
常见问题
Which page gets converted?
The page number you enter - page 1 by default. Run the tool again with a different number to export another page.
What resolution is the image?
Pages are rendered at 180 DPI, which is sharp on screens and good enough for slides and everyday printing. A standard A4 page comes out around 1240×1750 pixels.
Should I choose JPG or PNG?
JPG for pages that are mostly photos or where a smaller file matters. PNG (via the PDF to PNG tool) for pages with fine text, line art or diagrams, since it is lossless and keeps edges crisp.
Can I convert every page at once?
The tool exports one page per run so you can pick exactly what you need. For a multi-page export, repeat for each page number.
What does the quality setting do?
It controls JPG compression. Higher values give a sharper image and a larger file; the default is a good balance for screen use.
