How to Change a File Extension When It Is Not Displayed

By default, iOS does not display the file extensions for the most common file types like JPEG, PNG, AVI, MP4 and DOC, so when you try to rename them, you can only change the file name but not the extension. To fix this and to change the file extension of such files, you need to change a few settings. You should see all files with their extensions.

Using Third-Party Software

We recommend using iFiles for simplicity, but you can use alternatives, such as File Master or My File Organizer.

Using an Online File Converter

Use this method only if your files and documents are not confidential. If you’re looking for alternatives to FreeConvert, try one of the following websites:
