Image Resizer

Change the size of a photo in pixels — for a form that needs an exact size, a website, or social media. Keep the aspect ratio so the photo does not stretch, or set an exact width and height.

How to use

  1. Choose or drop an image.
  2. Enter the width, the height, or both in pixels.
  3. Keep "Keep aspect ratio" on to avoid stretching; turn it off for an exact size.
  4. Choose the output format and click Download.

How it works

With "Keep aspect ratio" on, the image is scaled to fit inside the width and height you enter. If you fill only one of them, the other is calculated automatically.

Tips and common uses

Resize for a form or portal

Application forms often ask for an exact size such as 200 × 230 pixels. Turn off "Keep aspect ratio" and enter both numbers. Crop the photo to a similar shape first so faces are not stretched.

Change only the width or the height

Fill just one box and leave the other empty. With "Keep aspect ratio" on, the other side is worked out for you, so the picture keeps its shape. The Aspect Ratio Calculator shows the numbers beforehand.

Size in pixels vs size in KB

Pixels are the width and height of the picture, KB is the file size. Making the picture smaller in pixels usually shrinks the file too. If you need an exact file size such as 50 KB, run the result through the Image Compressor.

Frequently asked questions

How do I resize a photo to 200 × 230 pixels for a form?

Enter 200 as width and 230 as height, and turn off "Keep aspect ratio" to get exactly that size. For a better result, crop the photo close to that shape first.

Does resizing reduce the file size?

Making an image smaller in pixels usually reduces the file size a lot. To reach a specific size in KB, use the Image Compressor.

Can I make a small image bigger?

Yes, but enlarging cannot add detail, so the image may look blurry.
