PDF to Images: Best Workflows for Web and Print
When to export PDF pages as images, which format to choose, and what settings avoid blurry results.
Why convert a PDF page to an image?
Converting PDF pages to images is useful when you need a preview thumbnail, want to post a page on social media, embed a page in a website, or share a single page without the full PDF. It can also help when a platform doesn’t accept PDFs but accepts PNG/JPG.
Choose the right output format
- PNG: best for text-heavy pages, charts, UI, and anything that needs crisp edges. Larger files, but sharper.
- JPG: best for photo-heavy pages where small artifacts are acceptable. Smaller files than PNG.
- WebP: good for web delivery when you want smaller files; great balance between size and quality.
DPI and resolution: what to use
DPI affects how sharp the exported page looks. Higher DPI increases clarity but also increases file size and export time. These are practical defaults:
- Web preview / thumbnails: 96–150 DPI
- Reading on screen: 150–200 DPI
- Print-quality exports: 300 DPI
If your export looks blurry, increase DPI or export at a higher pixel width. For text-heavy documents, prefer PNG.
Common mistakes to avoid
- Exporting text documents to JPG at low quality (creates artifacts around letters).
- Using very low DPI for pages that will be zoomed or printed.
- Exporting at huge DPI when you only need a small web preview (wastes size).
- Forgetting to check the result on mobile devices.
Best practices for web publishing
- Use PNG for crisp text and diagrams; use JPG/WebP for photo pages.
- Resize after export to your actual display width to reduce file size.
- Use descriptive filenames like
invoice-page-1.png. - Add alt text when embedding images in blog posts for accessibility.
Quick checklist
- Text/diagrams → PNG (or WebP lossless if available)
- Photo-heavy page → JPG or WebP
- Web preview → 96–150 DPI
- On-screen reading → 150–200 DPI
- Print → 300 DPI
- Verify the output on mobile before sharing
FAQ
Why does my exported page look blurry?
The DPI or output size is too low. Increase DPI (e.g., from 150 to 200) or export at a higher pixel width. For text, use PNG.
Should I use PNG or JPG for documents?
Use PNG for text and charts. Use JPG for photo-heavy pages where file size matters more than perfect edges.
What’s best for printing?
Export at 300 DPI. Keep PNG for text and diagrams, and ensure the final pixel dimensions match your print size requirements.
