Useful image math, without the clutter
Image Dimensions Toolkit turns common pixel, ratio, DPI, and print calculations into fast tools that work without an account.
Our purpose
Image dimensions are simple once the relationships are visible, but the information is often scattered across separate calculators or buried in editing software. This site brings those relationships together in one focused toolkit.
Privacy by default
When you choose an image, the browser reads its width and height locally. The file is not uploaded, stored, analyzed, or made available to the site operator. Every calculation also runs in the browser.
Accuracy and limitations
The formulas are deterministic and covered by automated tests. Print quality is still subjective and depends on the source image, printer, paper, sharpening, and viewing distance, so the site reports mathematical conversions rather than guarantees.
Independent project
This is an independent utility project. It is not affiliated with a printer, camera manufacturer, social platform, or image-editing application.
