Photo Size Converter

About This Tool

This tool converts photo size between units (pixels, inches, centimeters) and optional DPI, enabling precise sizing for web, print, and app assets. The process begins with width and height in a source unit and produces equivalent values in a chosen target unit. Outputs are numeric and ready for use in design specs or asset pipelines.
Conceptually, dimensions are normalized to a pixel basis using DPI when needed, then re-expressed in the target unit. This preserves the relationship between width and height and, by default, maintains the original aspect ratio.
Users such as photographers sizing images for banners, designers preparing print-ready assets, and developers integrating asset specs benefit from deterministic, unit-accurate results without editing the image data.
The tool emphasizes immediacy and repeatability: you enter numbers once, select units, and obtain precise conversions suitable for handoffs to printers, CMS, or layout software. It supports batch-like workflows as an extension and can export results for pipelines.
