Jpg file type not supported

[DaisyAge]

I've just downloaded Affinity for my MacBook, tried to open a jpg and I get this message: 

Failed to open file

/Users/XXX/Desktop/FUCS image.jpg

The file type is not supported.

Pretty frustrated as you can imagine! Where is it going wrong?! Other jpgs open. But this is the one I need! It's 17mb. Does that make a difference? Because the reason I wanted to open it was to reduce the size, ironically. 

P.S. I've tried searching other topics for this issue but I'm afraid I was unsuccessful. Apologies if this is a duplicate.

Hi DaisyAge,

Welcome to the forums

If you move the JPG to a different location on your computer does it work? If it doesn't please could you provide a copy of the JPG?

Thanks

Can you open the file with Apple's Preview app?

Is it that size because of its pixel dimensions, or because it’s uncompressed, or both? JPEG compression is usually ‘lossy’, but there is a lossless type of JPEG compression which isn’t widely supported.
