Image Resize

Resize and optimize images for web, mobile, and social content with precise target dimensions and controlled file sizes. The tool accepts common image formats and returns a resized asset with predictable performance characteristics. It is designed for developers, designers, content managers, and marketing teams who need assets that look consistent across platforms and load quickly. Core capabilities include dimension scaling, optional cropping, format conversion, and quality-based compression, all without altering the original file beyond the requested resize and encode steps. Use cases include website thumbnails, social previews, banners, and app icons.
Conceptually, the tool computes a scale factor to fit within requested width and height while preserving aspect ratio, then applies a final resize. If crop-to-fit is enabled, it crops the scaled image to the exact target box; otherwise it preserves the entire content with possible letterboxing. Compression is controlled by the quality setting and chosen output format (JPEG, PNG, WEBP), with WEBP often providing smaller sizes at similar visual quality. The workflow can preserve or strip metadata per settings; color space defaults to sRGB for web outputs.
