Screen Resizer Jar

The Screen Resizer Jar provides a precise, user-driven workflow for resizing screen captures and UI images to exact pixel dimensions. It targets designers, front-end developers, product managers, and content teams who need assets that conform to fixed sizes for previews, documentation, or platform-specific guidelines. Users upload one or more images, specify a target width or height in pixels, and choose whether to preserve the original aspect ratio or apply padding or cropping to fill the target frame. The tool then generates a resized asset in a chosen format suitable for immediate use in development pipelines or marketing materials.
Conceptually, the tool calculates a scaling factor based on the desired canvas size and the source image dimensions. When preserving aspect ratio and both dimensions are provided, it uses the smaller scale to ensure the image fits within the target box without distortion. If cropping is selected, the image is resized and then centrally cropped to the exact size; if padding is chosen, a neutral background is added to reach the target dimensions while the image keeps its proportions. It supports PNG, JPEG, and WebP, preserving transparency when applicable and applying sensible compression settings to balance quality and file size.
Core value lies in fast, predictable outputs, batch processing, and easy automation. Users can reuse presets for common sizes, export a ZIP of multiple assets, and integrate the resizing step into CI pipelines. Unique aspects include explicit control over aspect handling, padding options, and the ability to output multiple formats in one pass, reducing manual steps and ensuring consistency across products and campaigns.
