Image Size Converter

The tool converts image dimensions between pixel and physical units (px, in, cm, mm) and supports optional DPI input for accurate sizing. Conceptually, it treats width and height as measurable dimensions on a canvas and uses DPI to bridge between pixel-based and physical units. Designers, developers, and print specialists benefit from quick dimension checks, consistent asset sizing, and simplified asset handoff to developers or printers. Unique value comes from combining pixel-to-physical conversions with an aspect-ratio control that preserves the visual balance during resizing. Core features include source width/height inputs, unit selectors, an optional DPI input, and an output in the target unit. Use cases include preparing web banners, app icons, or print graphics where exact physical dimensions matter. The tool is calculation-focused, avoids image data manipulation, and integrates cleanly into asset pipelines as a dimension calculator rather than an editor. Users gain reliability in sizing decisions, faster iteration, and consistency across platforms and devices.
