Image Upscaler
Enlarge and upscale images to a higher resolution online.
This upscaler enlarges your image with high-quality smoothing and sharpening, right in your browser. It is great for making small images bigger without heavy pixelation. For photo-realistic AI upscaling of very low-resolution images, a dedicated AI service will go further.
Everything runs in your browser. Your image is never uploaded. Larger scales and bigger images take a moment to process.

Upload your image
Choose a JPG, PNG, or WebP image you want to make bigger.

Image Upscaler FAQ
Does upscaling make a blurry image sharp?
Upscaling makes an image larger and applies smoothing and sharpening to reduce pixelation, so it looks cleaner at the bigger size. It cannot invent detail that was never captured, so a very blurry or tiny source has limits. For heavy restoration, a dedicated AI upscaler goes further.
What is the difference from an AI upscaler?
This tool uses high-quality resizing plus sharpening in your browser, which is fast, private, and free. AI upscalers use trained models to add detail and can do more on very low-resolution images, but they are slower and usually upload your image to a server. Craftora keeps everything on your device.
What image sizes work best?
It works on any size, but the best results come from images that are already reasonably clear. Enlarging a small, sharp image looks great. Enlarging a tiny, blurry one improves the size but cannot fully restore lost detail.
Is my image private?
Yes. All processing happens in your browser on your own device. Your image is never uploaded to any server.
Do I need to sign up?
No. The image upscaler is free with no account and no limits.
