How does AI upscaling work?

BigImg uses deep convolutional neural networks to analyze your image and intelligently fill in detail when enlarging. Unlike traditional methods that simply stretch pixels, our AI reconstructs edges, textures, and fine details — resulting in a sharp, clean image with no blur or artifacts.

How is this different from Photoshop or other tools?

Traditional tools like Photoshop interpolate pixels by averaging colors, which produces blurry edges and visible noise at high magnification. BigImg's neural network has been trained on millions of images and understands the structure of lines, colors, and textures — so results are dramatically sharper with no "glitter" or ghosting.

Which types of images get the best results?

Anime and illustration images get near-perfect results — colors, edges, and fine lines are preserved beautifully. Photographs also upscale very well. For best results, avoid heavily compressed JPEGs with visible blocks.

How fast is the processing?

Processing typically takes 5–30 seconds depending on image size and scale factor. The AI model itself completes in under a second — the rest is server startup time. Pro users get dedicated warm servers that stay ready, delivering consistent 3–8 second results.

What is the maximum upload size?

Free users can upload images up to 10MB. Pro subscribers can upload images up to 50MB with no pixel limit.

Do I need to keep my browser open while processing?

If you are not logged in, yes — keep the tab open until processing is done. Logged-in users can close the browser; results are saved to your account history for download anytime.

Are my images kept private?

Yes. All uploaded images and results are stored with encrypted links — only you can access them. Images are automatically deleted from our servers after 3 days. We never share or use your images for any other purpose.

Why did my image fail to process?

Failures are rare but can happen due to network conditions or temporary server load. Simply wait a moment and try again — it almost always succeeds on a second attempt.

Do I need to create an account?

No account is needed for the 10 free daily uses. Creating a free account lets you track usage across devices and access your history. A Pro account unlocks faster processing and higher limits.

How do I get more than 10 free uses per day?

Upgrade to a Pro plan — you get a dedicated warm server, faster processing, higher upload limits, batch processing, and full image history.
