Part 3. FAQs of Changing DPI in Photoshop

How does changing the DPI affect the image resolution?

Increasing the DPI of an image improves its resolution and image quality. Higher DPI means more dots (pixels) per inch, resulting in a clearer image when printed. If you do this without changing the pixel dimensions of an image, the physical print size will be reduced.

Is 300 DPI equal to 300 PPI?

When it comes to specifying the resolution of an image, saying 300 DPI or 300 PPI generally conveys the same information; that is, the image contains 300 pixels per inch when printed or displayed.

How can 70 DPI be changed to 300 DPI?

To change the DPI (dots per inch) of an image from 70 DPI to 300 DPI, you can use Photoshop or GIMP. With Photoshop, you just need to change the resolution value to 300 DPI in the Resolution box under the Image Size window.
