[Gimp-user] FIle size jump when opening file

I work on tif files for work, and have noticed something that was not
present in previous versions of Gimp (2.8, for example).

The actual tif file size is 642KB. When I open it to edit it, Gimp is
stating in the bottom bar that this file's size is 681 MB, and while
editing the file, it is acting like it's 681 MB. It's slow and very
laggy to complete commands.

I've been using Gimp at work since 2012 and the most recent version of
Gimp has slowed down my workflow considerably.

Why does Gimp think it's editing a file this large when it's really

Thank you!

Best guess. Are they transmittals (or maybe archives), typically engineering
drawings 1 bit tiff files?

These are going to be opened in gimp as 8 bit and the file size correspondingly
greater. Example file size 11kb  in Gimp as a file in memory 30 MB.

After editing export as a CCITT group 4 and you should get back to a
corresponding small file size
