What Each Percentage Does
Scaling by a percentage changes width and height together, so the pixel count falls with the square of the percentage. Half the size means about a quarter of the pixels, and usually a much smaller file.
| Scale | 4000 × 3000 becomes | Pixels left |
|---|---|---|
| 75% | 3000 × 2250 px | 56% |
| 50% | 2000 × 1500 px | 25% |
| 25% | 1000 × 750 px | 6% |
| 10% | 400 × 300 px | 1% |
Tips for Best Results
- Keep the original picture so you can resize again for a different need.
- Resize down rather than up: enlarging cannot add detail.
- Use fill-and-crop for faces so nobody is stretched.
Limits and Things to Know
- Extreme changes in aspect ratio need cropping or extra space.
- Enlarged pictures look soft.
- Very large output sizes are limited to about 60 megapixels.
