Image file requirements

Each social network optimizes images so that they look their best on their platforms. Optimization methods include image resizing, reformatting, scaling, and cropping. The image upload requirements for each social network are listed in the table in this article.

You can upload an image from your computer or choose an image from the media library. Hootsuite lets you know if your images have any issues when you’re creating your content. And, in order to meet maximum file size requirements, we'll automatically compress images up to 20MB in size for you! (Note, however, that image compression is not supported for GIFs).

Tip: If you want more control over the final look of your images, edit them in the image editor. Use the Transform option to scale your images with aspect ratios made to fit each social network. See Edit your images in Hootsuite for more details.

Understand aspect ratio

An aspect ratio describes an image or video's shape using a proportional relationship between its width and height. Aspect ratios are written as a formula of width to height, like 3:1.

For example, a square image has an aspect ratio of 1:1. The height and width are the same. The image could be 200px × 200px, or 1600px × 1600px, and the aspect ratio would still be 1:1.

A portrait-style image might have a ratio of 2:3, where the height is 1.5 times longer than the width. So the image could be 500px × 750px, 1000px × 1500px, etc.
