I have problems opening JPG files sent by Android smartphones. In Photoshop it says that i's impossibile to open the image since it lacks SOFn, DQT or DHT marker before JPEG SOS marker.

In Lightroom these images are grayed out as not readable.

With Preview I can open these images.

Why not with Adobe apps? Any indication to solve the problem easily? Thanks !

Mac OS 10.14 / Photoshop CC


Solution 1:

I now understand that the problem lies in how Whatsapp saves JPG files, with a custom JPG format that is really a HEIC format. If you change the extension from JPG to HEIC, even Photoshop will read the file. I did a small Mac OS Automator app to change the file extension, that's useful if you have multiple "Whatsapp corrupted" JPG files.
