Free AI Image Upscaler
- Runs in your browser
- No sign-up
- Free, no watermark
Drop images to upscale with AI
Best for small photos, artwork and screenshots · JPG, PNG, WebP
Upscaling is GPU-heavy: expect 10–60 seconds per image depending on your device.
How it works
How to use the AI Upscaler
Choose a scale
2× suits most photos; 4× is best for very small images, icons and pixel art.
Drop images
Add one or several JPG, PNG or WebP images and click Upscale.
Compare & save
Drag the slider to compare, then download the enlarged PNG.
Why BGFixer
Built for real work, not just demos
Real AI enhancement
ESRGAN reconstructs edges and texture, giving sharper results than ordinary resizing.
Runs on your GPU
The model runs locally with WebGL, so there are no queues, credits or upload waits.
Queue several images
Add multiple images and they will be upscaled one after another.
Private
Your images never leave your device.

Frequently asked questions
How does AI upscaling work?
A neural network trained on millions of images predicts the missing detail when an image is enlarged, producing sharper edges than standard interpolation.
Is there a size limit?
To keep your browser stable, inputs are fitted to 1024px for 2×, 600px for 3× and 400px for 4× before upscaling.
Why is upscaling slow?
AI upscaling is computationally heavy and runs on your own device. A modern laptop takes 10–30 seconds per image.
Is the AI upscaler free?
Yes, with no watermark and no limits.
