Title: File Format Error on downloaded photos
Post by: drazenmd on August 23, 2016, 04:00:06 AM
Hi Phil and Exiftool community,
I have some photos which I downloaded from phone backup and I can't open them now. With EXIF tool I get "File Format Error". Can you please check what is problem with these photos.
Regards

A quick look shows that it's missing the jpeg id pattern at the start of the file.  I also looked for a more obvious jpeg chunk marker and didn't see any.  Hopefully, someone with more experience will check it out but I think the file has been too corrupted.

Like stargeek, I too had a look at the file, but it looks like the file is really corrupted; I can not find a JPG in there either. Perhaps Phil is able to find it, but he is currently away so it may take a while for him to have a look at it.

Thank you for fast action. It's really a bad news. Is it possible to get preview of this file?

The problem with your file is that there is no discernible (jpg) image data. Thinking differently here, could it be that the file is encrypted?

It shoudn't be encrypted. Some files from that location I can open and some no. Is it possible to copy exif data from picture which I can open to another one dameged. It's same camera that made photos

I'm afraid these files are beyond repair (if they really are image files). I think there was something wrong with your backup; the filename doesn't look right either...

Found the problem. this is a webp file with a .jpeg extension
Something similar you should encounter downloading 500px images by the way...

That is not a WEBP image.  ExifTool supports reading WEBP files, and would tell you if it was a WEBP file.
