Can this tool change the DPI?
This tool checks DPI only. To change DPI, use image editing tools like Photoshop or GIMP.
What is the difference between DPI and PPI?
DPI refers to print output; PPI refers to screen display. They are often used interchangeably.

Why does my image show 72 DPI?

πŸ’‘ 300 DPI for print

Always use 300 DPI images for professional print materials β€” brochures, business cards, and posters.

πŸ’‘ 72-96 DPI for web

Web images don't need high DPI β€” 72-96 DPI is standard. Higher DPI only increases file size.

πŸ’‘ Upscaling doesn't help

Increasing DPI without adding real pixel data doesn't improve print quality.

πŸ’‘ Camera raw files

Photos taken with a DSLR typically have enough pixel data for 300 DPI prints.

Checking image DPI is essential before submitting files to print services, photo labs, or publishers who require specific resolution standards.
