Upscale and enlarge images online using AI-powered super-resolution. ToolzStack Image Enlarger increases resolution by 2x, 4x, or 8x while preserving sharpness and detail. Perfect for photos, product images, and digital artwork.
Unlike Photoshop's simple bicubic interpolation, ToolzStack uses AI super-resolution which reconstructs missing detail. Compared to Topaz Gigapixel (paid desktop app), ToolzStack is free and requires no installation, though Gigapixel may produce slightly better results at extreme scales.
