Sub Resizer

Sub Resizer enables precise image resizing across multiple target dimensions without manual trial-and-error. Conceptually, it accepts a source image, applies a chosen sizing mode (fit, crop, or stretch), and outputs one or more resized assets suitable for web, mobile, or social channels. The tool supports batch processing with presets to accelerate repetitive tasks. In fit mode, the output maintains the original aspect ratio and sits within the target frame; in crop mode, the image is resized to cover the frame and cropped according to a crop_focus setting; in stretch mode, width and height are adjusted independently, potentially altering the aspect ratio. Advanced options include crop focus (center, top, bottom, left, right), output format (jpeg, png, webp), quality, and optional metadata handling. Use cases include generating responsive images for a website, creating square thumbnails for galleries, and producing app icons at standardized sizes. The unique value lies in combining multi-target batch resizing with precise aspect-control, preserving transparency where applicable, and delivering ready-to-publish assets with consistent sizing across platforms.
