From the developer
Syed Balkhi's own description of File Upload Types by WPForms, lightly tidied.
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.
How WordPress File Uploads Work
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.
How does the File Upload Types plugin work?
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.
What file types can I upload to WordPress with this 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:
.ai
.zip
.xml
.svg
.csv
.mobi
.cad
.dwg
.dxf
…and any other file extensions that exist, including custom file types.
We hope that you find the File Upload Types plugin helpful!
