Use Cases and Applications
Quality vs Size Trade-offs
| Aspect | PNG | JPG | Best For |
|---|---|---|---|
| File Size | Large | Small | JPG for photos, PNG for graphics |
| Quality | Perfect | Good | PNG for graphics, JPG for photos |
| Transparency | Yes | No | PNG for transparent images |

Checklist
- Determine if conversion is appropriate for content type
- Check if transparency is required
- Choose appropriate quality settings (80-90%)
- Handle background/transparency if needed
- Test converted JPG quality
- Compare file size reduction
- Verify compatibility with target platforms
- Consider alternative formats (WebP, AVIF)
- Test on different devices and browsers
- Document conversion settings
Troubleshooting
- Quality too poor after conversion: Increase quality setting, check original PNG quality, avoid multiple conversions
- Transparency lost: Add solid background before conversion, use PNG for transparent images
- File size not reduced enough: Lower quality setting, check if content is suitable for JPG
- Blurry text or graphics: Keep PNG format for graphics, only convert photographs
