Thanks

You won't be able to "compress" by simply zipping the file since most picture/video formats are binary and are already designed to efficiently use minimal space. Your options are to change formats or change the picture format image compression. In both cases, you'll lose some quality.

As for compressing, you aren't going to do it at upload via a php script. Prior to upload, the user will need to do the compression before contacting the server. If you are hosting the image, your php script could kick off a backend server process to compress the image format, but that wouldn't make a lot of sense since you generally won't want to do that for every request for the file (unless you come up with a caching policy to minimize server processing).
