What is DPI / PPI?
DPI (Dots Per Inch) and PPI (Pixels Per Inch) measure the pixel density of an image. In printing, DPI refers to the physical dots of ink a printer places in one square inch, while PPI refers to the number of digital pixels in that same inch.
The industry standard for high-quality printing (like magazines or photos) is 300 PPI. Anything lower may appear blurry or pixelated when printed.
Calculating Print Size
To determine how large you can print an image without losing quality, divide its pixel dimensions by the desired resolution.
For example, a 3000x2400 pixel image printed at 300 PPI will yield a high-quality 10x8 inch print. If printed at 150 PPI, it could be 20x16 inches, but the quality would be lower.

Zero file uploads. When you check your image's DPI, the file is never uploaded to a server. OmniTools reads the metadata locally using your browser's File API, ensuring your personal photos remain completely private.
