How to Restrict Uploads to Specified File Types Only in WordPress

Few days ago while working on a client’s site, we were asked to code a function that restrict uploads to specified file types only (jpg, gif, png). After looking around the repository and finding nothing that can do this, we decided to create a plugin of our own. Yesterday, it was approved in the WordPress plugin repository and it is called Restrict Uploads.

Unlike other plugins, this plugin does NOT have a super complex settings panel. As a matter of fact, it doesn’t have any settings panel at all. It is built to do one thing and one thing only. That is to keep your editors from uploading any other file type aside from images (jpg, gif, png). Plugins like these are the ideal type because it works silently in the background having no impact on your site’s load time, or your day to day activity.

All you have to do is simply install and activate the plugin. Download Restrict Uploads Now.

  2. @susan suarez Yes you are correct. This will prevent any malicious entry using the wp-admin to upload stuff using the media uploader…

  3. Very handy – thanks for adding this. Would this also help with the security of the plugin? So that if a hacker got in, they couldn’t upload any other type media file?

  4. @wpbeginner You’re right…. I wanted to focus on .JPG, .PNG and .GIF in capital… coz they can’t be uploaded. Some image editors save in capitals…

  5. @Debajyoti Then there would be no point of having this plugin. The whole idea is to keep the editors from uploading any other file type aside from images. We will work on an improvement for this plugin that will let you pick which users to limit the stuff for though :)

  6. @JasonDittmer Yea I love plugin like these myself. Because they don’t require you to do anything. It is for one thing only.

  7. I was expecting to read about how I had to write a bunch of code to make this work. Thanks for the simple plugin. Nice quick fix!
