Enlarge images up to 4× without blurring.
Most resize tools stretch pixels and blur the result. This one rebuilds detail at 4× — sharp edges, recovered texture, faces that hold up at larger sizes.
How it works
- 1Upload a small image
The enlarger works on images up to 512×512 px — thumbnails, cropped portraits, old scans, low-resolution downloads. Larger images should be cropped first.
- 24× scale is set automatically
The tool reconstructs fine detail at four times the original dimensions, not just bilinear stretching. A 256×256 thumbnail becomes a 1024×1024 image with recovered edges and texture.
- 3Download the enlarged result
Direct download, no watermark. Compare with the original in the preview.
What you get
- 2× or 4× upscaling with AI — not blurry bilinear stretch
- Sharp edges, fine texture recovery, and face detail
- Best for thumbnails, icons, cropped portraits, and scanned art
- Accepts images up to 512×512 px
- Free, no account required
Frequently asked questions
- What is the difference between enlarging and upscaling?
- They mean the same thing — increasing the pixel dimensions. The key question is how: naive stretching (bicubic, bilinear) blurs; AI upscaling reconstructs expected detail based on what the subject looks like.
- What is the size limit?
- Input images must be 512×512 px or smaller. If your image is larger, crop or resize it before uploading. The output will be up to 2048×2048 px at 4×.
- Can it sharpen a blurry photo?
- Enlarging and sharpening are related. Enlarging recovers expected detail on small, undersampled images. For motion-blurred or out-of-focus photos, the Unblur Photo tool is a better starting point.
