Do you need to upload files to your website that are normally not supported by WordPress?
You can upload many common file types in WordPress, including images, videos, audio files, and office files. However, some website owners need to upload files that are unsupported.
In this article, we’ll show you how you can add additional file types for upload in WordPress.
Which File Types Are Allowed for Upload in WordPress?
To keep your site secure, you can only upload the most commonly used file types to your WordPress website. There is also a maximum size limit on the files that can be uploaded.
By default, the allowed file types and extensions are:
Images: .jpg, .jpeg, .png, .gif, .ico
Documents: .pdf, .doc, .docx, .ppt, .pptx, .pps, .ppsx, .odt, .xls, .xlsx, .PSD
Audio: .mp3, .m4a, .ogg, .wav
Video: .mp4, .m4v, .mov, .wmv, .avi, .mpg, .ogv, .3gp, .3g2
Tip: Although you can upload videos to WordPress, we recommend using a video hosting site instead. This helps protect your website’s speed and performance.
However, some file types have the potential to be misused and can be a security risk, so WordPress doesn’t enable them by default:
Images such as .svg, .bmp
Documents like .psd, .ai, .pages
Code files such as .css, .js, .json
Video like .flv, .f4l, .qt
If you try to upload unsupported file types to your WordPress website, then you will see the error message, ‘Sorry, you are not allowed to upload this file type.’
But what if you need to upload an unsupported file type? You could upload the files through FTP or your WordPress host’s file manager, but that’s not as convenient as using the built-in WordPress media library or a file upload form.
Let’s take a look at how to add additional file types to be uploaded in WordPress.
How to Add Additional File Types to be Uploaded in WordPress
First, you need to install and activate the free File Upload Types by WPForms plugin. For more details, see our step by step guide on how to install a WordPress plugin.
It’s one of the best file upload plugins and is the easiest way to add support for additional file types to WordPress. It was co-created by WPBeginner’s founder, Syed Balkhi.
Using Preset File Types
Upon activation, go to the Settings » File Upload Types page in your WordPress admin area. Then, simply scroll through the list of preset file types, or enter a file type into the search box.
Next, check the boxes next to the file types that you want to enable.
Once you’re finished, you need to click the ‘Save Settings’ button at the bottom of the screen to store your changes.
Now you will be able to upload those file types using the WordPress media library.
Adding Custom File Types
If the file type you want to add wasn’t included in the list of presets, then you can add it as a custom file type.
When you scroll down to the bottom of the File Upload Types screen, you will come to a section labeled ‘Add Custom File Types’. Here you can add a file type by entering a description, MIME type, and file extension.
To add another custom file type, simply click the ‘+’ icon at the end of the line. When you’re done, don’t forget to click on the ‘Save Settings’ button to store your changes.
For example, if you wish to add the YAML file type, then you would type ‘YAML file’ in the description, ‘text/yaml’ in the MIME type field, and ‘.yaml’ as the file extension.
MIME (‘Multipurpose Internet Mail Extension’) is a standard way to identify files on the web. The easiest way to learn a file’s MIME type is to use a MIME File Type Checker.

‘Sorry, this file type is not permitted for security reasons.’
/********** code used ***************/
//Adding different file format

WPBeginner Support says
You would want to reach out to your hosting provider, they are likely overriding the files allowed to be uploaded

Allow All File Types
You can also setup WordPress to allow to upload all file types. This can be performed with the help of a WordPress constant “ALLOW_UNFILTERED_UPLOADS”. You can set the WordPress constant “ALLOW_UNFILTERED_UPLOADS” to true” in wp-config.php file of your WordPress install. The wp-config.php file can be found in the root directory of your WordPress install. Using your favorite editor (vi editor) open the wp-config.php file and add the following line somewhere in the file. You can also use File Manager to edit the WordPress configuration file.
define(‘ALLOW_UNFILTERED_UPLOADS’, true)
Don’t forget to save the config file after editing.
WPBeginner Support says
The dangers of a method like this would be that you are allowing every file type to be uploaded to your site which removes some safety.

I still cannot get csv uploads to work in 4.9.9 upwards of wordpress. Has anyone got a solution? Just adding the csv type to the list doesn’t seem to help. Is csv explicitly banned in the core somewhere.
Sam Bean says
Is all this still good for WordPress 4.9.2? I also could not find any mime types for Adobe Illustrator files (.AI and .EPS)
Can you tell me what I would add to the file to be able to upload those 2 file types?
Ajeet says
hello sir,
i want to upload .exe file,but it shows an error.So what can i do
WPBeginner Support says
Hi Ajeet,
You cannot upload it by default. You will need to allow .exe file types first. Please see the instructions in the above article.

Diana says
Thanks for this article, I used it today! I have a question. I had to allow .sql file types to be uploaded to wordpress, in order to upload some of my scripts that I would like to share.
The problem is, if I put the script in a link, when I click on the link, the script downloads automatically, instead of opening in a new window.
This is the code I added:
function my_myme_types($mime_types){
$mime_types[‘sql’] = ‘text/x-sql’; //Adding sql extension
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
When can I change the behavior? Also after the file is uploaded it says it is SQL type.
Thanks
Diana
Darren says
So, it would be nice if we knew where to add the code??????????????????
Thanks
WPBeginner Support says
All custom code in the article goes into your theme’s functions.php file or a site-specific plugin

Kevin says
At the bottom of the functions.php page. At the top? Is there already a place I add them to, like under the allowed file types already there? (jpg,gif,mp4,etc…)
I’ll try at the bottom and see what happens.
Kevin says
Worked. For the people wondering. I just scrolled to the end of that page and pasted the code in there. If you copied and pasted the code up there, don’t be like me and leave the numbers. Just erase the numbers.
And if you’re like me, you just skimmed through to find what you’re looking for. I couldn’t find what I had to put so it would open the right program, it’s in that link that’s hidden between the snippets of code up there. “File extensions” is what you’re looking for. Go to that page and look up your extension you want to add, I wanted to add KML and KMZ for my wiki on a stick and it looks like this…
function my_myme_types($mime_types){
$mime_types[‘kml’] = ‘application/vnd.google-earth.kml+xml’; //Adding kml extension
$mime_types[‘kmz’] = ‘application/vnd.google-earth.kmz’; //Adding kmz files
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
All I did was copy and past the code up there and changed the file extension and the… other part. Worked like a charm.
Oh, the finctions.php is in appearance -> Editor -> On the right side of that page, Theme Functions (functions.php). Just scroll to the end of that page and add your code there.
Bruno says
Kevin, whats your WP version? Mine is 4.2.4 and it doesnt work!…
Jeremy Taylor says
Adding the code looks pretty easy but it is not clear where I should add the code. Where do I go from my dashboard to add it? I’m using WordPress 4.3.1.
Thanks
Jeremy
Kymmie says
Go to Appearance > Editor > Look for functions.php and just add the code to the bottom. Don’t forget to put a label like
//Adding different file format
so you would know.
Bry says
Hi There.
Thanks for the really useful information…
I managed to get the different file types (.IES and .LDT files) to upload ok following your advise above but unfortunately they do not download as files, but rather as code….any tips on how to fix this issue?.
Thanks in advance for your help.
Regards
Bry
Bry says
This is the code i used in the theme-function.php file..
function my_myme_types($mime_types){
$mime_types[‘ies’] = ‘application/octet-stream’; //Adding .ies extension
$mime_types[‘ldt’] = ‘application/octet-stream’; //Adding .ldt extension
return $mime_types;
}
add_filter(‘upload_mimes’, ‘my_myme_types’, 1, 1);
Sara says
THX. That’s useful
WPBeginner Staff says
Yes, CSS.
Mark Gandy says
How do you get the file type’s small icon (the file type logo) to load automatically where it will be positioned next to the name of the file (which is a link)? I’m guessing that’s CSS?
