What This Tool Does
This tool loads an SVG file directly in your browser using URL.createObjectURL and img.decode() for reliable, guaranteed non-blank rendering. It presents an interactive crop overlay with draggable handles, and converts the selected area to a next-gen AVIF file. No server upload is required. The full workflow — loading, rendering, cropping, encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. The output uses the browser's native AVIF encoder via canvas.toBlob('image/avif'), producing a compact, high-quality AVIF file suitable for modern web delivery.
Who This Is For
- Web developers who need to export a specific region of an SVG as an optimized AVIF image for production delivery
- Designers who want to rasterize and crop an SVG to AVIF without installing Photoshop or Inkscape
- Anyone optimizing image assets for Core Web Vitals who needs to trim SVG content to only the relevant area
- Front-end teams replacing PNG or WebP assets with AVIF using SVG source files
