When to Convert PDF to Images
- Presentations — embed PDF slide content into PowerPoint or Google Slides
- Thumbnails — generate preview images for a document management system
- Social media — share a certificate, chart, or infographic without requiring a PDF app
- Email attachments — some email clients block PDF attachments; JPGs always display inline
- OCR preprocessing — convert to image before running through text recognition
JPG vs. PNG: Which to Choose?
| Format | Best for | Tradeoff |
|---|---|---|
| JPG | Photos, scanned pages, color-rich documents | Lossy compression — slight quality loss |
| PNG | Text-heavy documents, diagrams, screenshots | Larger files, lossless |
For documents with crisp text (contracts, invoices), use PNG. For photo-heavy documents where file size matters, use JPG at 90%+ quality.
DPI and Resolution
DPI (dots per inch) controls output resolution:
- 72 DPI — screen-only thumbnails, very small files
- 150 DPI — web display, email-friendly size
- 300 DPI — print-quality, standard for archiving
- 600 DPI — high-fidelity archiving, very large files
A standard A4 page at 300 DPI outputs a 2480 × 3508 pixel image — enough for crisp printing.
