Image Resize Target

The tool computes recommended target dimensions for an image given platform constraints and a maximum file size. It accepts original width and height in pixels, an optional aspect ratio lock, and a maximum file size in KB. Conceptually, it treats the problem as a size-constraint optimization: preserve aspect ratio when requested, fit within max width/height bounds, and approach the desired file size through a quality/compression heuristic. The core outputs are target_width_px, target_height_px, and estimated_size_kb, along with a flag indicating whether the constraints were met. This supports workflows for web pages, apps, and social media where exact dimensions and file sizes impact loading speed and rendering. A key value is providing a reproducible starting point for editors and pipelines, reducing iteration. Unique value comes from combining dimension fitting with a size-driven adjustment pathway, rather than only resizing by fixed presets. Typical use cases include preparing a hero image to fit within a 1024x768 container while staying under a platform limit, or generating a 1:1 avatar with a given maximum file size. Core features include dimension calculation, aspect ratio handling, and a concise notes field for guidance, with export-ready numeric outputs for downstream tools.
