New DPI
Pixels and the picture do not change at all — only the DPI written in the file, which sets the print size (cm).

Frequently asked questions
Will my photo get sharper at 300 DPI?
No. DPI only tells printers how big to print it. To change sharpness or size, change the pixels in Resize Image.
A form asks for 200 DPI. Is this enough?
If the pixels are right, yes — this writes 200 DPI into the file. Check the pixel or cm size the form wants too.
