Date: 2019nov11 Language: html Keywords: upload Q. html <input type=file> accept files by extension A. The accept= attribute appears to want MIME types but recently, for uncommon types (ie not JPEG) I have found that just the extension works best. eg to only allow Photoshop files:

<input type='file' accept='.psd'>

Rather than

<input type='file' accept='image/vnd.adobe.photoshop'> WRONG

Or other MIME types.
