Frequently asked questions
Does 300 DPI make my photo sharper?
No. DPI only sets the print size; sharpness depends on the pixels.
Are the pixels changed?
No. Only the density fields change; the picture data is copied byte for byte.
Is my original changed?
No. A separate copy is made; your original stays as it is.
