DPI vs PPI: What’s the Difference?
DPI and PPI are related, but not identical. DPI describes printer dots per inch on paper, while PPI describes pixels per inch on screens.
DPI = Print Output
When you print, printers place tiny dots of ink or toner. DPI determines how tightly those dots are packed.
PPI = Screen Density
On phones, monitors, and laptops, PPI describes pixel density. It impacts visual sharpness on screen devices.
Common Confusion
Changing DPI metadata without enough pixels does not create real detail. Always check dimensions and intended output size.
Practical Workflow
- Check current file with DPI Checker
- Adjust using Change DPI Tool
