Our AI Image Upscaler enlarges your photos up to 4x their original resolution using browser-based Canvas API with intelligent sharpening. Unlike cloud-based services, your images never leave your device.
The upscaler uses Canvas API with high-quality interpolation to enlarge your image, then applies a sharpening convolution filter to enhance details. You can adjust sharpness intensity for optimal results.
You can upscale images by 2x, 3x, or 4x their original resolution. For example, a 500×500 image at 4x becomes 2000×2000 pixels.
No. All processing happens 100% in your browser using JavaScript Canvas API. Your images never leave your device.
You can upload JPG, PNG, WebP, GIF, and BMP images. Export is available in PNG, JPG, and WebP formats with adjustable quality.
Upscaling with sharpening can improve perceived quality, but it cannot recreate detail that was never captured. Best results come from images that are small but already clear.
Since processing happens in your browser, very large images (over 10,000px) may be slow depending on your device. There is no hard limit imposed by the tool.
