00:00In this video I'm going to show how to limit file uploads by format.

00:10I will try to upload an image with PNG format.

00:20This is the error message.

00:25Now let's see the code.

00:29From MyView application I'm sending a simple file object using FormData object and Axios.

00:46In Django I'm getting from the request the image and using this function to verify if the image has the expected format.

01:10First I'm verifying by extension.

01:16Then I'm checking if the MIME type of the uploaded image is within a predefined list of allowed types.

01:35Now I have only one format for extension and to add more I will do this.

01:52Finally I will try again to upload same image.

02:00Now the image was uploaded.
