Need an image that is exactly 300x300?
A 300x300 image is exactly 300 pixels wide and 300 pixels tall. That gives it a 1:1 aspect ratio, making it a practical square format for profile images, avatars, thumbnails, product images, directories, and other layouts that require equal width and height.
Upload your image above, resize it to the target dimensions, check the result, and download the finished image.

300 × 300 explained
What does 300x300 pixels mean?
The first number represents the width and the second represents the height.
So an image that is 300x300 contains a 300-pixel width and a 300-pixel height. Because both measurements are identical, the resulting image is square.
This is different from resizing an image to a particular file size such as 100 KB. Pixel dimensions describe the physical image grid, while KB describes how much storage the image file uses.

300x300 pixels is not the same as 300 KB
This distinction matters. 300x300 describes an image's pixel dimensions. 300 KB describes the file size. An image can be exactly 300x300 pixels and still have a file size that varies depending on its format, image content, and compression.

Is 300x300 a good image size for a profile picture?+
