Gigantic JPEG File Size

  • October 11, 2019

I receive an A4 size menu artwork in JPEG format from a client. I am not sure what software he used to create the work, but the file size is a gigantic 313.6MB for such a small dimension at 300ppi.

 

What is the reason for such huge file size? I believe there must be some information embedded within the file.

 

I try to resave the file but it doesn't help at all.

Try exporting the file using Save for Web. Does it reduce dramatically. If so the issue is likely to be ancestor metadata.

 

See here on scripts to remove it:

I had to take down the script samples, I can post a copy of them if there is interest, the new forum format has most likely broken the links.

      Save for Web does the trick by bringing the filesize all the way down to 5MB.

      Btw, where do all these ancient metadata come from? What advice should I give to the client in order to prevent such issue from happening again?

      Thanks.

      It comes in with imported images and can build up with multiple imports. The scripts linked can remove it without stripping other metadata.
