Image Dimension Converter

This tool solves the problem of sizing digital images for both screen and print by converting dimensions between pixels and physical units using a user-specified DPI. It accepts width and height in pixels or inches and returns consistent values in all supported units, enabling precise asset preparation across channels.

Core logic: for each dimension, inches = pixels / DPI and pixels = inches × DPI. If both width and height are given in mixed units, the tool resolves them using the same DPI. Optional advanced feature preserve_aspect_ratio scales the other dimension proportionally when only one side is provided.

Users benefit from consistent sizing across platforms, faster asset preparation, and reduced risk of mis-scaled images. The outputs are rounded to two decimals and can be copied or exported. Validations guard against missing DPI, negative or zero dimensions, or invalid inputs. When conflicting inputs occur, the tool prioritizes pixel-based values and reports a minor discrepancy within a tolerance.

Audience includes graphic designers, web producers, and print coordinators. The unique value lies in combining both pixel and physical unit conversions with clear outputs, eliminating the need for separate calculators and ensuring alignment between on-screen proofs and printed assets.
