How to Convert PDF to JPG in High Quality (300 DPI)
Converting a PDF to JPG is easy. Getting a sharp JPG, where small text and fine lines stay crisp, takes the right settings. This guide explains which options matter and how to get the best result.
The settings that control quality
Two settings decide how good your image looks:
- Resolution (DPI) sets how many pixels each page gets. More pixels means more detail.
- JPG quality sets how strongly the image is compressed. Lower quality means smaller files but more visible artifacts around text.
Recommended settings
| Purpose | DPI | Quality |
|---|---|---|
| Printing | 300 | High |
| Presentation slides, documents with small text | 300 | High |
| Viewing on screen, email, upload forms | 150 | Medium or High |
| Thumbnails and quick previews | 72 | Medium |
Convert step by step
- Open PDF to Image and choose your PDF.
- Set Format to JPG, Resolution to 300 DPI and Quality to High.
- Click Convert and wait while each page is rendered.
- Click a preview to download one page, or Download all (ZIP).
How big will the images be?
At 300 DPI an A4 page becomes about 2480 × 3508 pixels. Depending on the content, a JPG at high quality is often between 0.5 and 3 MB per page. Pages with photos are larger than pages with plain text. If that is too big, 150 DPI produces a quarter of the pixels and is still sharp on screens.
When PNG is better than JPG
JPG is designed for photos. On pages that are mostly black text on white, JPG compression can create faint blotches around letters, especially at lower quality. PNG is lossless, so text edges stay perfectly clean. Choose PNG for documents, diagrams, charts and slides; choose JPG when the page contains photos or file size matters. Our comparison of JPG, PNG and WebP explains the differences in detail.
Why going above 300 DPI rarely helps
For text documents, the source PDF usually contains vector text, which looks sharp at any size. 300 DPI is already more than most printers and screens can show. Higher values mostly create huge files. The exception is scanned PDFs: their quality is limited by the original scan, and no export setting can add detail that was not captured.
Getting just one page
The tool converts all pages and lets you download each one by clicking its preview. If your PDF is very long and you only need a few pages, extract them first with Split PDF to save time.
Summary
For high-quality JPGs, convert at 300 DPI with High quality. Use 150 DPI for on-screen use and smaller files, and switch to PNG when your pages are mostly text or diagrams.
