Practical guide for PDF 转 JPG
Example use case
Turn a one-page flyer PDF into a JPG preview for a website thumbnail or social media post.
Settings explained
- Resolution controls pixel dimensions and sharpness.
- JPG quality controls file size and visible compression.
- Higher resolution is better for print previews, while lower resolution is better for web thumbnails.
Limitations
- JPG does not support transparency.
- Very high resolution exports can use significant browser memory.
- Selectable text becomes pixels in the exported image.
Troubleshooting
- If text looks soft, increase resolution before exporting.
- If files are too large, lower JPG quality or resolution.
- If transparency matters, use PDF to PNG instead.
