Frequently asked questions
- Will upscaling make a small photo sharper?
- No. Missing pixels cannot be invented; enlarging blurs. Use it to shrink.
- Will it distort the image?
- Enter only width or only height and the other side follows automatically. Entering both forces those exact dimensions.
- Does enlarging make a small photo sharper?
- No. New pixels are invented, so the result is softer. Only enlarge when you have to.
- How do I match a photo spec given in millimetres?
- At 300 dpi one millimetre is about 11.8 pixels, so 35 by 45 mm is roughly 413 by 531 pixels.
