The "300 DPI" Myth

On Screens (Web/Phone)

DPI metadata is IGNORED. All that matters is pixel dimensions (e.g. 1920x1080).

In Print

DPI MATTERS. It tells the printer how many pixels to squeeze into one inch of paper.

Wait, my client is asking for "300 DPI"!

If a printer or client asks for an image at 300 DPI, they usually just mean "Make sure the image is large enough" (pixels). Ideally, you don't need to "convert" the DPI metadata; you just need enough pixels.

Example: If they want an 8x10 inch print at 300 DPI, you need an image that is 2400 x 3000 pixels (8*300 by 10*300).
