Useful takeaways from this story.

A dimmed screenshot file with a random extension often only needs a manual rename to.png to become usable.

If the problem recurs, update macOS and verify screenshot format settings (switch back to PNG or JPG if currently PDF/TIFF).

The useful part

Fix Mac not saving usable screenshot image files in Finder In this quick troubleshooting guide, we explain what to do if you take a screenshot on your Mac, but the saved file is grayed out and won't open as an image. When you take a screenshot, you expect the image to save to your desktop or the Finder folder you set as the save location. However, if you haven't restarted your Mac in a long time or Finder is glitching, the image file may appear as if it wasn't saved as an image.

How it works

  • After renaming, confirm that you want to use the new extension by clicking " Use png." The screenshot should be normal now, and you can open it in Preview, Photos, and other apps.
  • Click the Apple icon  in the top left corner and select Force Quit.
  • Save your ongoing work in other apps, then restart your Mac.

What to take from it

Screenshot file grayed out on Mac If you're facing this problem, the fix is quick and easy. In case you took a bunch of screen captures, and they all have this problem, I recommend trying the next method first. Relaunch Finder Usually, the screenshot doesn't save properly because of Finder glitches.

Example or evidence

  • Instead, it will be dimmed/grayed out and have a non-PNG extension like " png-urliu3 " or something random.
  • It may also have dots (or) at the start of the file name, which makes macOS treat it as an invisible system file.
  • These fixes should also help if you downloaded a file using Safari, Chrome, or Firefox but it has a random extension and seems unusable.
  • Rename the file manually This is the easiest fix, provided the dimmed-out screenshot file appears on the screen (if not, see the next tip: relaunch Finder).

Details worth keeping

Plus, this approach is practical only if one or a few screenshots have this issue. Remove any extra dots,, and text at the beginning of the file name before the word 'Screenshot.' Remove any extra words after the actual '.png' extension. This tip also helps if you take a screenshot, but the file seems absent.
