AI Image Upscaler – Enlarge Photos 2x or 4x
Make your images bigger without the blur. Our free upscaler uses the Real-ESRGAN AI model — a neural network that reconstructs realistic detail and sharp edges as it enlarges, far beyond what plain stretching can do. Enlarge 2× or 4×, compare with a drag slider, and download. Very large images automatically fall back to high-quality resampling so the tool stays fast and reliable. No sign-up and no watermarks.
How to Upscale an Image
- Click the upload area above or drag and drop your image (up to 3 MB).
- Choose 2× or 4×, and drag the compare slider to preview the enlarged result next to the original.
- Click Download Upscaled Image to save it instantly.
Key Features
- AI Upscaling (Real-ESRGAN) – A neural network reconstructs detail and sharp edges, not just bigger pixels
- 2× and 4× Enlargement – Double or quadruple the width and height
- Before / After Compare Slider – Drag to see the result against the original
- Keeps Your Original Format – Saved in the same format you uploaded, with transparency preserved
- No Watermarks – Clean output, completely free
Common Use Cases
- Enlarging small images for display or moderate-size printing
- Scaling up thumbnails or web images for higher-resolution screens
- Making small product images big enough for zoom views
- Enlarging graphics or screenshots for presentations
- Getting a low-resolution photo to a usable larger size
Supported Formats
You can upload JPG/JPEG, PNG, or WebP (and other common raster formats), up to 3 MB — a tighter limit than our other tools because enlarging is memory-intensive. Your upscaled image is saved in the same format you uploaded. For larger files, shrink them first with our Compress Image tool.
Frequently Asked Questions
Plain resizing just stretches the existing pixels. This upscaler runs your image through the Real-ESRGAN AI model, which reconstructs detail and sharp edges as it enlarges — so results look much crisper than a simple stretch. Our Resize Image tool is the one to use when you just need an exact custom width and height.
Yes — the Real-ESRGAN model was trained to reconstruct plausible texture and sharp edges, so it adds convincing detail rather than just enlarging pixels. It works best on photos and graphics; extremely blurry or tiny sources have less to work with. Very large uploads use high-quality resampling instead, to keep processing fast.
Up to 4× the original resolution — for example, a 500×500 image becomes 2000×2000.
3 MB per image for this tool, since enlarging uses more memory than other operations. For larger files, compress them first with our Compress Image tool.
