I usually use Clipboard to check the image size. I always thought my screenshot image too large, like follow this, have 19.8 MB, I hope find a method to reduce the size.

Today I take the screenshot save as a file. My computer display the size, more lower than the clipboard, just is 433 KB, I consider my computer display error.

I upload the image to the Cloud OSS, At last, I found this is the Clipboard display error, My computer don't have problem!

 

I think the Clipboard just according the dimensions computer the size. Your Clipboard have this issue?

That’s not unusual. If you copy image data, like a screenshot, most applications store it on the clipboard as TIFF data, and TIFF images are very large compared to JPEG/PNG.

 

From my tests, Alfred also saves TIFF data when a PNG representation is available. That may be because PNG is lossy relative to TIFF. Perhaps @Andrew can clarify?

Thx your reply. May be clipboard saves TIFF data, But I can't find the setting that about the TIFF data, I think through Clipboard to check the size of image is a good idea. May be Alfred can provide a switch setting, give user a choice.

Which setting? To be clear, Alfred doesn't decide what format the data is. The application it's copied from does, and TIFF is the standard format.
