Receiving base 64 image in Web API

I have to create a Web API (I'm using ASP.NET Core 1.1), and one of the things it needs to be able to do is t receive a JPEG image (and later also other document types such as PDF). The front end developer (using Angular2) said he will send the image to the API in Base64. I had previously created a controller action in my API that accepts an IFormFile, but the front end developer said he doesn't know how to send the API in this way. So I now need to modify my API to accept a Base64 image. Can I have a simple controller action in the API which reads the body of the POST request, and then converts that into a file? So:

// POST: api/images
    [HttpPost]
    public async Task<IActionResult> PostImage([FromBody] Base64Image image)
    {
        byte[] bytes = Convert.FromBase64String(image);
        using (MemoryStream ms = new MemoryStream(bytes))
            Image image = Image.FromStream(ms);

        return CreatedAtAction("PostImage", new { id =  123});
    }

Should that do the trick?
