AI Image Upscaler

Increase image resolution with AI

The Soft Premium Tools AI Image Upscaler makes a small or low-resolution image 2× or 4× bigger using Real-ESRGAN, an AI model trained to enlarge photos. Ordinary resizing just stretches the pixels, so enlarged pictures look soft or blocky. The AI model sharpens edges, rebuilds textures and reduces JPEG artefacts as it enlarges, so the result looks clearer. It runs in your browser: your image isn’t uploaded.

How to upscale an image

1. Choose an imageClick the box, drag a file onto it, or paste one. JPG, PNG or WebP up to 20 MB.
2. Pick 2× or 4×The finished size is shown before you start, for example 1,000 × 750 px becomes 2,000 × 1,500 px at 2×.
3. Choose the modelBest quality (ESRGAN Medium) or Fast (ESRGAN Slim) for older devices.
4. CompareDrag the slider, view side by side, and zoom to 100% or 200% to check fine detail.
5. DownloadAs PNG, JPG or WebP, without the preview watermark.

What it’s good for

• Product photos

  Enlarge supplier or phone photos for online shops and marketplaces. Check labels and logos afterwards.

• Old and small photos

  Make low-resolution pictures from old phones, scans or the web big enough to print or share.

• Social media and websites

  Get sharp images for banners, thumbnails and posts from a small original.

• Artwork and graphics

  Enlarge drawings, game sprites and digital art with cleaner edges than ordinary resizing.

What AI upscaling can and can’t do

AI upscaling adds detail that looks right, based on what the model learnt from many photos. It is not the original detail, which a small image never contained. It works best on clear but small pictures. It can’t fix badly blurred or out-of-focus photos, and it may slightly change small text, logos, product labels and faces, so check those before you publish or print the result.

Sizes and formats

The output is exactly 2 or 4 times the width and height. Because the AI runs on your own device, images can be up to 2,048 px on their longest side for 2× and 1,024 px for 4×, so results are at most 4,096 px wide. With a graphics card it usually takes seconds. Without one it’s slower, so the Fast model helps. You can download PNG (keeps transparency), JPG (smaller, transparent areas become white) or WebP. Camera and location details (EXIF) aren’t copied into the result. To crop or change the format without upscaling, use the Image Cropper; to make a file smaller, use the Image Compressor.

Price, privacy and licences

Upscaling and comparing are free to try. Each downloaded image uses 1 export, and downloading the same image again within 24 hours is free. See pricing. Your image stays on your device. The preview carries a watermark; no website can reliably block screenshots, so nothing is ever charged for one. The AI models (UpscalerJS ESRGAN) are MIT-licensed and run on TensorFlow.js (Apache 2.0), so you can use your results commercially as long as you have the rights to the original image.
