How to resize image by percentage
- 1Upload your image.

- 3The aspect ratio is always preserved, so nothing gets distorted.
- 4Choose a format and download.
Resizing by percentage is the easiest way to make an image proportionally bigger or smaller when you do not care about a specific pixel size — you just want it, say, half as large. Because it scales width and height together, the image never looks stretched.
Enter any percentage from 1% up to 200%. Everything runs locally in your browser using the HTML canvas — your image is never uploaded to a server, so it stays completely private and there is no waiting for uploads.
Scaling down keeps images crisp. Scaling above 100% enlarges pixels and can look soft — for big enlargements start from the highest-resolution source you have.
Need to change the shape, not just the size?
When you resize to a different aspect ratio, you normally have to crop or add bars. Our AI outpainting tool generates new matching background so your photo fills any canvas without losing a thing. Sign in for 3 free AI generations.
