Hello!

quick question: is it possible to restrict the file-type which can be selected by the user in an asset field? Like: only jpg and png. Or only pdf…

Thanks!

You can’t restrict, which files are selectable, but you can restrict the upload via config.yaml.

```auto
# define allowed file types for uploads (global)
assets.allowed_uploads: png, jpg, jpeg

# define allowed file types for uploads (for user groups)
groups:
    author:
        $admin: false
        $vars:
            assets.allowed_uploads: png, jpg, jpeg

```

If you’re looking for a way to apply this kind of filter, i found that it works like this :

On your assets field, click the “options” tab, then insert the filter you need.

For images :  
`{`  
` filter: {`  
` type: 'image'`  
` }`  
`}`

For videos :  
`{`  
` filter: {`  
` type: 'video'`  
` }`  
`}`

For pdf :  
`{`  
` filter: {`  
` mime: 'application/pdf'`  
` }`  
`}`

Multiple types :  
`{`  
` filter: {`  
` $or: [`  
` { type: 'image' },`  
` { mime: 'application/pdf' }`  
` ]`  
` }`  
`}`

Hope it helps !
