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 any image
Thumbnails, cropped portraits, old scans, and low-resolution downloads gain the most — real detail recovery, not just a bigger blur. Larger photos are downscaled automatically before the 4× pass, so nothing gets rejected.
- 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.

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?
- Everyday photos are accepted and downscaled to a bounded working size before the 4× pass, so output tops out around 2048×2048 px. Very large files — over 25 MB or very high resolution — are refused; resize those first.
- 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.
