When do you need to convert PDF to image?
- Extracting charts or diagrams from reports to use in presentations
- Sharing a specific page from a report on social media
- Creating preview thumbnails of PDF documents
- Embedding PDF content in platforms that don't support PDF (Instagram, WhatsApp)
- Converting scanned PDFs to images for further processing
- Archiving documents as images
Resolution guide (DPI)
| DPI | Use case | File size |
|---|---|---|
| 72 DPI | Screen display only, web thumbnails | Small |
| 96 DPI | General screen use | Small–Medium |
| 150 DPI | Good quality for most purposes | Medium |
| 300 DPI | Print quality, high detail | Large |
For most purposes, 150 DPI provides a good balance of quality and file size.
Image format guide
- PNG: Lossless, best for text and diagrams, larger file size
- JPG: Lossy, best for photos and complex graphics, smaller file size
- WebP: Modern format, excellent quality-to-size ratio, broad browser support
How to convert PDF to image free
- Go to PDF to Image
- Upload your PDF
- Select pages to convert (all, single, or range)
- Choose output format (PNG recommended for quality)
- Set resolution (150 DPI recommended)
- Adjust quality slider for JPG/WebP
- Download individual images or all as ZIP
PDF to image vs taking a screenshot
Screenshots capture whatever the screen renders — at screen resolution (typically 96 DPI). This is fine for web use but looks blurry when printed. Converting via a proper tool at 150–300 DPI produces sharper output by rasterizing the PDF at the target resolution directly, bypassing screen rendering entirely.
Multi-page PDFs — batch processing
For a 10-page report, "download all as ZIP" creates a ZIP file containing 10 numbered images (page-1.png, page-2.png, etc.). This is the fastest way to extract all pages without downloading one at a time.
Preparing PDF images for OCR
If you're converting a scanned PDF to images in order to run OCR (optical character recognition) on them, use 300 DPI and PNG format. Lower resolution reduces OCR accuracy. PNG (lossless) preserves text edges better than JPG for OCR purposes.
File size expectations
A standard A4 page at 150 DPI in PNG is roughly 1–2 MB. At 300 DPI it's 3–6 MB. If file size is a concern, use JPG at 85% quality — visually indistinguishable from PNG at a fraction of the size.
