Resize your image

This image resize tool converts an input image to a user-specified width, height, or scale, producing a web- or print-ready asset. It accepts JPEG, PNG, and WebP formats, preserves color profile when available, and returns a resized file along with resulting dimensions and encoding. The workflow is strictly dimension-focused and non-destructive to the original file when re-run.
Conceptually, the tool computes target dimensions from inputs and preferences. If keep_aspect_ratio is true and only one dimension is provided, the other is derived from the original aspect ratio. If both width and height are provided, the tool preserves aspect ratio by adjusting the unconstrained dimension accordingly. After dimensions are determined, the image is resampled with a standard interpolation method and optional format conversion and quality settings. This approach minimizes distortion while meeting exact size constraints. The tool benefits web developers, designers, and content teams aiming to optimize assets for speed, layout accuracy, and platform requirements.
Core differentiators and capabilities include precise pixel control, automatic aspect-ratio handling, optional format conversion, and metadata management. It supports single image workflows with straightforward inputs and can be extended to batch scenarios via integration. Common use cases include resizing banners to 1200x630, creating square thumbnails at 512x512, or converting a PNG to WebP to reduce file size. Edge cases are addressed: zero or negative dimensions are rejected; missing image or dimension inputs are flagged; very large inputs are processed in streaming fashion to avoid memory issues.
