Image format calculator - calculate aspect ratio, megapixels and print size

Image format calculator is a comprehensive online tool that allows you to calculate the aspect ratio of a photo, its resolution in megapixels and the size of a possible print at a specific DPI in just a few seconds. Perfect for photographers, graphic designers, printers and anyone who wants to precisely scale an image while maintaining its quality and proportions. Available without registration onwebp.pl.

How does the image format calculator work?

The tool analyzes the dimensions of the photo - its width and height - and automatically calculates several key technical parameters:

Aspect ratio- e.g. 4:3, 16:9, 3:2, 1:1;
Resolution in megapixels (MPix)– ideal for assessing the quality of photos from cameras and smartphones;
Print size at a specific DPI– e.g. 300 DPI for photo printing or 72 DPI for the web;
Scaling on the longer side– allows you to reduce or enlarge the photo while maintaining the proportions.

Calculator operating modes

The calculator operates in two modes -AnalysisandScaling on the longer side:

Analysis mode

In this mode, the tool analyzes the entered values and provides data on format, megapixels and aspect ratio. It allows you to quickly determine the orientation (vertical/horizontal) and recognize popular formats such as 16:9, 3:2, 4:3.

Rescale mode

Allows you to calculate new image dimensions after changing the length of the longer side - without losing quality and maintaining the original proportions. Perfect for preparing photos for social media, portfolio or printing.
