What causes the “Sorry, this file type is not permitted for security reasons.” error?
By default, WordPress only lets you upload a limited selection of file types:
- Document: .pdf, .doc, .docx, .ppt, .pptx, .pps, .ppsx, .odt, .xls, .xlsx, .psd
- Images: .jpg, .jpeg, .png, .gif, .webp, .ico
- Video: .mp4, .m4v, .mov, .wmv, .avi, .mpg, .ogv, .3gp, .3g2
- Audio: .mp3, .m4a, .ogg, .wav
The restriction exists to prevent hackers from exploiting files on your website. ?️
Certain file types like SVG are vulnerable and can be corrupted easily because these file formats were not created with security in mind. So if you upload them to your website, hackers will exploit the files to gain access to your site. That’s why WordPress allows only a handful of file types to be uploaded to a website.
If you try to upload a restricted file type, it shows you the “sorry, this file type is not permitted for security reasons.” error.
