Each social network has a different format, and adapting your image to publish it in the ideal size can be long. There is a tool that allows you to change the size of your image in a single click to fit the different formats of each social network.
How does it work? You simply upload the image and the site will present you with all the available formats, select the format or formats that interest you and click on download.
And the best thing, it’s free, without registration and gives a good result.
