What is DPI?

DPI describes print dot density or image density metadata. Print quality also depends on pixel dimensions, source quality, print size, printer and media.

What is PPI?

PPI (Pixels Per Inch) describes how densely pixels are packed on a physical display. It depends on both screen resolution and physical screen size.

What is Resolution?

Resolution describes pixel dimensions such as 1920 × 1080. Visible detail also depends on source quality, compression, scaling and output size.

What is Aspect Ratio?

Aspect ratio is the proportional relationship between an image’s width and height (e.g. 16:9, 4:3, 1:1). It determines the image’s shape.

FAQ & SUPPORT

Frequently Asked Questions

Find quick answers to common questions about image details, DPI, print size calculations,
and how our tool works.

No. Your images are analyzed directly in your browser using modern web technology. Nothing is uploaded to our servers, so your files stay private and secure.

Aspect ratio is calculated by comparing an image’s width to its height, expressed as a ratio (e.g. 16:9, 4:3, 1:1). We simplify the numbers to their lowest terms for easy reading.

DPI (Dots Per Inch) is used for printed images and refers to the number of ink dots per inch. PPI (Pixels Per Inch) refers to the pixel density of a digital image displayed on a screen.

Many images from the web, screenshots, or social media do not contain DPI metadata. In these cases, DPI is not available because it’s optional information and not required in all image formats.

Yes. You can calculate physical print size, convert pixels to inches, and compare image dimensions with a selected print-density value. Final print quality also depends on the source image and printing process.

Yes! Our image detail checker and all tools are completely free to use, with no sign-up required. You can analyze images, check details, and calculate print sizes instantly.
