While digging more, I found that I could even quickly resize the images on my browser itself, without too much hassle. To overcome these issues, I started looking for a better solution and I came across the FileReader API, which allow users to process images (multiple of course) on their computer itself, without having to upload the images to a server. Most importantly, if your website still uses http instead of https (secured protocol), the new updated browsers would show a Not secure message on the browser's address bar. The entire process is relative slow and less secure. This requires space (to store the images), you have to write server side code to monitor the process, remove the images after some time, and this can sometimes create security issues. Many online image resizing tools, that I have come across, load the images on a remote server, as it process the images at the server side.
