Resize image dimensions

This tool computes target image dimensions for assets used in web and print. It accepts an original width and height, a desired width and height, and a unit selector (default pixels) with an optional DPI for print. It also offers a toggle to preserve aspect ratio. Conceptually, it derives a dimension pair that matches the constraints without touching the actual image data. This is especially useful for content teams coordinating across web CMSs, design systems, and developer pipelines. The tool outputs the final width and height, the resulting aspect ratio, and guidance on export settings for web or print. Unique value lies in its precise, repeatable calculations and compatibility with CSS/HTML attributes, file-naming conventions, and asset pipelines. Core features include input validation, aspect-ratio handling, and DPI-aware calculations. Use cases include preparing hero images for a responsive site, thumbnails for galleries, or banners that must fit exact slots while preserving visual integrity.
