You can rename files in your galleries by hovering your mouse cursor over an image and then clicking on the three-dot menu. There you can conveniently change the name by clicking on “Rename file.” Once you have changed the name, simply click on “Rename” and you’re done!
This is also possible in the three-dot menu in the single image view.
It’s important to note that the filter function within Lightroom and other tools will no longer work if you have changed the file names. Because it is obviously necessary that the file names remain identical to those in your other tool e.g. Lightroom.
You can only use this feature if you purchased a Pro, Pro+ or Business plan.

You can also rename multiple files at once. You first select the files you’d like to rename, then pick the rename option in the toolbar. Now you can type in the name and a rename with ongoing numbers for example.
