浏览器内运行这个工具能做什么
Convert each page of a PDF to high-resolution PNG or JPEG files, review scale and format settings, and export in your browser. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Processing runs in the current browser tab, so the practical limit is your device memory and browser support rather than a server quota.
这个工具可以完成什么
Convert PDF pages to images for use as preview thumbnails in a web application or document viewer.
Export specific PDF pages as images to share content on platforms that don't support PDF uploads.
Convert a full-page infographic from a PDF report into a standalone PNG for use in presentations.

Convert a full-page infographic from a PDF report into a standalone PNG for use in presentations.

使用技巧
PNG preserves sharp edges and text. JPEG produces smaller files but with slight compression artifacts.
Use 300 DPI for images intended for printing. 72–96 DPI is sufficient for screen display.
常见问题
What image formats can I export?
JPEG and PNG are supported. PNG is recommended for documents with text or crisp graphics.
Can I convert specific pages to images?
Yes. Use the Pages input in this tool, for example all, 1-3, or 2,5,8-10, before exporting.
Are my files uploaded during conversion?
Conversion runs in your browser. Tool code processes selected files and entered content in your browser and does not submit them to a TOOLGRID processing endpoint.
Why does the converted image look blurry?
Increase the DPI setting for sharper output. The default DPI is optimized for screen viewing.
