SUMMARY Attempting to save an existing TIFF image as JPEG (JFIF) results in an error: "Unsupported Image Format" and "Saving ‘1920_01_23_0024.jfif’ failed: Unsupported image format". Saving to other formats seems to be working correctly.

Can you share a tiff file to test with ?

Sorry if I wasn't clear in my report, it happens on every and any files, regardless of original format, whether a screenshot from Spectacle, a gif from the web, or a picture from a camera phone. So it's not something related to the specific file.

When you choose the output name I guess Qt or Gwenview tries to find the image format based on the file extension, but this is not a image file extension AFAICT so it fails logically. I was able to reproduce the issue trying to save a png to a .jfif file, it is expected, although the error could be more explicit.
When I select "JPEG Image" from the dropdown of "File type" the "Automatically select filename extension" says "(.jfif)". No where do I say use .jfif. Manually changing the extension in the Name box does not allow me to save the image as a .jpg or .jpeg. See attachment. There is certainly a bug here, resetting to Reopened.

Duplicate report at: https://bugs.kde.org/show_bug.cgi?id=446887 Workaround at: https://bugs.kde.org/show_bug.cgi?id=439519 I can confirm the workaround works for me. It appears the problem is more related to the Applications->File Association settings. *** This bug has been marked as a duplicate of bug 439519 ***
