That’s because you cannot change server settings on free hosting. It’s not possible to increase the upload limit on free hosting.
If you need to install a large plugin or theme, you may be able to extract it on your own computer and install it manually. If you are looking to upload large files to share on your website, please use a specialized file sharing service like Mediafire.
