About this extension
Instagram Image Upscaler and Downloader adds an Upscale button to Instagram photos.

When you press the button, the current image is processed locally in your browser with WebSR and WebGPU when available. If WebGPU is unavailable, the extension uses a CPU fallback.

Features:
• Choose 2× or 4× upscale.
• Mouse-wheel zoom, drag to pan, and middle-click to reset.
• Full-screen image view.
• Download the upscaled result as a PNG.
• Works with individual posts and carousel images.

The extension does not upload images to an external AI service.
