Does changing DPI improve image quality?

Changing only DPI metadata does not create new pixels or detail. The pixel dimensions determine how much image information is available.

Why does my image have no DPI value?

Some formats or export workflows omit DPI metadata. The file can still have valid pixel dimensions.
