I have a form in which a user is suppose to upload a .ppm file and I am suppose to convert the file to a valid .png file at the time of the upload.
I know how to do so with ImageMagic but in this case I don't have the liberty to install anything on the server, no PHP module or anything else.
I also cannot run any CLI command - only via the browser.
under these circumstances is there a way?
I didn't find a good way to do what I wanted without ImageMagic but the webhost finally agreed to install ImageMagic so I guess case closed
