Photo Size Editor DPI

Purpose and user intent: The tool enables precise control of image pixel dimensions and DPI for print or digital delivery. It targets photographers, designers, and marketing teams who must guarantee that assets meet print sizing and web display requirements. Core functionality includes adjusting width and height in pixels, setting DPI, and selecting an export format with a color profile hint. The approach communicates real-world print size derived from pixels and DPI, enabling predictable results.
Core logic and features: Users can preserve aspect ratio or override it, choose a resampling method (nearest, bilinear, bicubic, Lanczos), and specify an output format. The tool maintains data integrity through validation and reports derived metrics such as print size.
Use cases and value: Before printing a brochure, a designer converts 3600x2400 at 300 DPI to printable size, or resizes gallery assets for a web page at 72 DPI while preserving visual fidelity. The unique value is explicit DPI-aware resizing tied to print sizing, not just pixel scaling.
Core features and workflow: input targets (width_px, height_px, dpi), optional aspect controls, quality/format selection, and export. Outputs include final pixel dimensions, DPI, print size in inches or millimeters, and estimated file size for planning and handoffs.
