If your image is smaller than 400x400 pixels, the tool will upscale it and show a warning before download. Since profile pictures are displayed as a circle, use Fill mode and keep your face or logo centered so nothing important is cropped from the corners.

400x400 pixels is the recommended profile picture upload size on X (Twitter) and is commonly used as a reference size across other platforms as well. Even though profile pictures are often displayed much smaller, such as 48x48 pixels in a feed, uploading at 400x400 gives the platform more pixel data to work with. This results in a sharper image on high-DPI Retina displays, where smaller uploads can look blurry or pixelated when scaled up.
If your image is smaller than 400x400 pixels, this tool will upscale it to fit and show a warning before download. For profile pictures, upscaling a small photo or logo can introduce visible softness, especially since most platforms display the image as a circle and crop the corners. For the sharpest result, start with a source image that is at least 400 pixels on its shortest side and keep your subject centered, since circular cropping removes the corners of a square image.
Yes. Most platforms display profile pictures as a circle, which crops out the corners of a square image. Use Fill mode to crop your image to a perfect square while keeping the center intact, and make sure your face or logo is positioned in the middle of the frame before resizing. Anything near the corners of the original image will not be visible once the circular crop is applied.
