Reduction of dimensions in a JPEG image

Question

I have to reduce the dimensions of a JPG image to exactly 350 * 450 pixels.Please tell how do I do so.My JPG image is of dimensions 392*520 pixels.

UPDATE:

Ok, thanks for the answers . Checking them now. Thanks.

Answer 1

You can use paint. Go to the resize button (on top of the rotate button) and click the radio box that says pixels. Choose the amount of pixels you want.

Answer 2

You can't do that with a linear operation, the ratio of the image will be skewed. There is nearly 3 % absolute difference, I don't know how much that is to the human perception.

350/392 =  0.8929
450/520 =  0.8654

I would recommend scaling it to 89% and then cut the rest of the image to get your 350 * 450. This way you would keep the ratios intact.

Answer 3

There are many online resize tools, e.g.: http://www.picresize.com/

Upload your image, enter its new dimensions and download it again.
