How It Works
Upload your image
Drop a JPG, PNG, or WebP file up to 10 MB. Need to convert from another format first? Use the image converter or RAW to JPG tool.
Choose scale factor
Select 2× to double pixel dimensions, or 4× to quadruple them. Not sure what size you need? The DPI Calculator tells you the maximum print size at any resolution.
Download enlarged image
The AI-upscaled JPG downloads instantly. Use the Image Comparison tool to verify quality, or compress the JPG if you need a smaller file size.
What Is AI Upscaling?
jpg.now uses an advanced AI super-resolution model trained on millions of real-world image degradation examples. Unlike bicubic interpolation - The standard algorithm in most image editors - Our AI reconstructs high-frequency texture detail that simple math cannot recover. The result is sharper edges, finer texture, and more natural-looking enlargements at 2× and 4× scale. If your source image is a RAW camera file, convert it to JPG first, then upscale. If it's a PNG with transparency, convert PNG to JPG before upscaling, or keep it as PNG for the final output.
When to Use AI Upscaling
| Use Case | Recommended Scale | Typical Input | Result |
|---|---|---|---|
| Large-format printing | 2× or 4× | Small digital photo | Print-ready at poster/canvas size - Check DPI with the DPI Calculator |
| E-commerce product images | 2× | 720p product shot | Clean 1440p for marketplace listings - Pair with background removal |
| Old or scanned photos | 4× | Low-res scan or vintage photo | Recovered detail, reduced JPEG artefacts |
| Social media thumbnails | 2× | Cropped portrait or product | High-DPI display ready - Check platform size requirements |
| Presentation screenshots | 2× | 72–96 DPI screenshot | Retina-quality in slides |
| Heavily compressed web images | 4× | Small JPG with visible artefacts | Smooth texture, artefact reduction - Recompress after to manage file size |
2× vs 4× - Which to Choose?
2× Upscaling
Doubles pixel dimensions. A 1000×800 image becomes 2000×1600. Fast processing, ideal for photos that need a moderate size boost - print exports, marketplace listings, Retina display assets. Use the file size calculator to estimate the output size before upscaling.
4× Upscaling
Quadruples dimensions. A 500×400 image becomes 2000×1600. Best for very small sources, heavily compressed files, or scans where maximum detail recovery is needed. After upscaling, use JPG compression to reduce the larger file to a web-friendly size.
Before and After
Use the Image Comparison tool to inspect your upscaled result against the original side by side - Drag the slider to see exactly where the AI recovered detail. Works directly in your browser with no upload to a server.

Frequently Asked Questions
For most photos, yes. Photoshop's default Bicubic Smoother algorithm is a mathematical interpolation - It estimates missing pixels based on surrounding colour values, which produces smooth but blurry results at large scale factors. AI super-resolution uses a trained neural network that recognises image content and reconstructs plausible detail. The difference is most visible in textures, hair, foliage, and fine patterns.
Yes, but there are diminishing returns. AI upscaling adds the most value when the source image lacks high-frequency detail - Small files, heavily compressed JPEGs, or scanned prints. Upscaling a sharp 4000px photo to 8000px will make it technically larger but won't add meaningful new detail. In that case, 2× is a better choice than 4×, and you may not need upscaling at all.
Input: JPG, JPEG, PNG, WebP - Maximum 10 MB per file. Output is always a high-quality JPG. If you need a PNG output with transparency, upscale first then use the JPG to PNG converter. For RAW camera files, convert to JPG first then upscale.
Free accounts get 3 upscales per day. The quota resets at midnight UTC. Premium plans start at 200 upscales per month. See the pricing page for plan details.
The key is to use AI super-resolution rather than standard resizing. Standard resize algorithms (like bicubic or bilinear) spread existing pixels across more space, which blurs fine detail. AI upscaling analyses the image content and reconstructs texture, sharpness, and edge definition that wasn't present in the original file. Upload your image above, choose 2× or 4×, and download the result - Quality is preserved at the enlarged size. Full guide →
Yes - AI super-resolution specifically addresses quality loss during upscaling. Traditional resizing loses quality because it has to invent pixel data it doesn't have. AI models trained on large image datasets learn what enlarged textures, edges, and details should look like and reconstruct them rather than guessing. The result is a larger image that looks naturally sharp rather than blurry or pixelated. More detail →
For print enlargements: upscale first using AI (use 4× for small originals), then check the output resolution using the DPI Calculator to confirm it meets your target print size at 300 DPI. Export at the highest quality JPG setting or convert to TIFF using the JPG to TIFF converter for lossless print delivery. Start from the highest-quality original you have - Never upscale from a compressed web thumbnail if the original file is available. Full guide →
