File Upload Types by WPForms


WordPress File Upload Types plugin

Do you want to let your WordPress website accept uploads from your users for more file types and to freely upload files? We created the File Upload Types plugin to make it simple for anyone to easily add support for any file types with any extension or MIME type.

Hoe File Upload Types werkt

By default, WordPress only allows certain file types to be uploaded to your website’s media library.

If someone tries to upload a file type outside of these whitelisted WordPress file extensions, this can be the cause of the common WordPress error Sorry, this file type is not permitted for security reasons message.

It can be frustrating if you’ve created a file upload form in WordPress but the file type you want to accept is a file extension that’s not allowed.

This plugin lets your website upload more file types beyond the limited file extension types that WordPress allows by default.

Hoe werkt de plugin File Upload Types?

The File Upload Types plugin works by letting you adjust the internal file whitelist, letting you manually control which types of file extensions your WordPress website can upload.

This way, you can accept any file type through your website and/or any contact form plugin like WPForms.

Welke bestandstypes kan ik uploaden naar WordPress met deze plugin?

The File Upload Types plugin lets you allow uploads of any file extension, including custom file types.

Some common file extension types this plugin lets you add that WordPress doesn’t support natively include:


… en alle andere bestaande bestandsextensies, inclusief aangepaste bestandstypes.

We hope that you find the File Upload Types plugin helpful!

Having problems uploading permitted file types or with a big file upload?

Hosts can also limit the maximum file upload size you can accept.

Works as intended. Great support. Thanks.

I think the idea is good if it worked. I can't use it to upload .ai files, or .cdr even by creating custom filetypes.

This plugin worked perfectly for me and was easy to use. I only used it for an epub (and you do have to select the correct file extensions in settings before it will work) but I'm very happy with the result. The epub downloads fine.

It works but I mean why is this just not built into the main plugin. Makes no sense. There's a breaking point where keeping wordpress lightweight becomes more of a nuisance than it's worth.
