Upscale Image
Enlarge photos 2× or 4× with sharpening.
Uses high-quality resampling and unsharp-mask sharpening in your browser. It makes edges crisper; it can't recreate detail that isn't in the photo.
Your files are processed on your device and are never uploaded.
Upscale a small image to 2×, 3× or 4× its size with smooth, high-quality resampling and sharpening. Make low-resolution photos, logos and screenshots big enough for printing, presentations, wallpapers or a website, without the blocky look of simple stretching.
How to Upscale an Image
- Choose your image.
- 4× enlargement is already selected – choose 2× or 3× if you need less.
- Adjust sharpness and clarity while comparing the before-and-after zoom.
- Click Enhance & save and download the larger image.
What to Expect
- Edges and text become larger and stay crisp instead of pixelated.
- Upscaling cannot invent detail that was never in the photo – a tiny, blurry image will look smoother, not perfectly sharp.
- 4× multiplies the pixel count by 16, so files get much bigger – reduce them afterwards with Reduce Image Size in KB if needed.
