Quill Image Resize

Purpose: provide accurate image sizing for Quill editor content. The tool accepts original image dimensions and target dimensions, then applies aspect ratio and fit rules to output new dimensions. It serves editors, developers, and marketers preparing assets for CMS templates.
Core capabilities include required inputs (original_w, original_h, target_w, target_h, keep_aspect, fit_mode) and outputs (new_w, new_h, scale, mode). Advanced users can opt into percentages or alignment to guide cropping.
Algorithms maintain predictable results: when keeping aspect with contain, the image fits inside the target box with possible padding; with cover, the target is filled, potentially cropping edges. Non-aspect resizing uses exact target_w and target_h.
Use cases include pre-sizing images before inserting into Quill content, batch resizing via API for asset pipelines, and ensuring uniform grid alignment across articles. The tool is language- and locale-agnostic beyond pixel units, and integrates with standard Quill workflows.
Limitations: no actual pixel data manipulation is performed here; outputs are dimensions and optional alignment data for downstream processing and insertion.
