At A Glance (Key Takeaways)
- PPI (Pixels Per Inch) measures digital display density on screens and monitors.
- DPI (Dots Per Inch) refers to physical ink droplets sprayed by a printing press or inkjet printer.
- Simply changing the DPI metadata tag from 72 to 300 without increasing pixel dimensions does NOT make a blurry image sharper.

The Great Myth of Changing 72 DPI to 300 DPI
If you have a 300 × 300 pixel thumbnail and you change the file header to 300 DPI, your image does not magically gain extra detail. Instead, the printer will simply print that 300 × 300 image as a tiny 1-inch square postage stamp!
To achieve true 300 DPI at physical print sizes (such as 8x10 inches), you need 2400 × 3000 actual digital pixels. PixEnhance helps you calculate the exact pixel count required for any physical print size.

Frequently Asked Questions
Does DPI matter for photos displayed on websites and social media?
No. Screens completely ignore DPI metadata tags. They only care about pixel width and pixel height.
