Phone photos are JPGs; applications want PDFs. And sometimes you need the reverse — a PDF page as a JPG to share on WhatsApp or upload as an image. Both conversions should keep sharpness and keep file size sane.
JPG to PDF: When & How
Use cases: passport photo to PDF, certificate photo to PDF, scanned notes to single PDF, invoice image to PDF for email.
- Open JPG to PDF → Upload 1–50 images (JPG/PNG/WEBP).
- Drag to reorder — first image = first page.
- Settings: Page size: A4 for forms, Fit image for photo prints; Margin: Small (5mm); Orientation: Auto.
- Click Convert → Single PDF downloads. Each image fills one page, centered.
PDF to JPG: Export Pages as Images
- Open PDF to JPG → Upload PDF.
- Choose DPI: 150 DPI for sharing/web (smaller files), 300 DPI for print/re-upload.
- Convert → Download each page as JPG or ZIP if multi-page.
Tip: Exporting a 10-page PDF at 150 DPI gives ~150KB per page; at 300 DPI ~500KB per page — pick based on where you’ll upload.
Quality, DPI & Page Size Settings
| Need | Recommended | Why |
|---|---|---|
| Government form (PDF under 200KB) | JPG→PDF at 150 DPI → Compress 200KB | Balances legibility + size |
| Print / Xerox | 300 DPI | Sharp print at 300 PPI |
| WhatsApp / Email share | 150 DPI JPG | Small, fast to send |
| Signature/photo close-up | Fit image + 0 margin | No wasted white border |
Batch Conversion Tips
- Name files 01_front.jpg, 02_back.jpg before upload to get correct order automatically.
- For 50+ photos, split into 20-image batches → merge PDFs after with Merge PDF.
- iPhone HEIC? Allow browser to convert — quality stays at 90% JPEG.
- Need exact size after? Use Compress Under 500KB as final step.
