Batch Resize Images
Resize multiple images to specific dimensions for consistent display across your website or application.
Convert Image Formats
Convert images between formats like PNG, JPEG, WebP, and AVIF for optimal compatibility and performance.
ToolDifferent contexts demand different image formats. WebP and AVIF deliver smaller file sizes for the web but are not universally supported. PNG preserves transparency for overlays and icons. JPEG offers the best compatibility for photographs. SVG scales infinitely for logos and icons. Choosing the right format for each context directly impacts page load speed, visual quality, and bandwidth costs.
ToolRouter's transform_image skill converts between all major image formats while letting you control quality, compression, and metadata handling. You can convert a single image or describe a batch conversion rule -- for example, converting all PNG product photos to WebP for your website while keeping PNG originals for print.
Format conversion is a fundamental step in any image pipeline. Modern web performance best practices recommend serving WebP or AVIF to supported browsers while falling back to JPEG or PNG for older ones. Automating this conversion ensures your images are always in the optimal format without manual intervention.
