Let’s take a look at how to change image resolution in WordPress image galleries.

Select any image in the gallery. Go to the Settings tab on the right sidebar. Find the Resolution option and click the dropdown icon.

Finally, use balanced image resolution for clear visuals and fast loading. Avoid very large images when not needed. Match resolution with gallery size. Test loading speed after changes.
Unless proper resolution settings are used and configured, galleries will fail to show your image’s sharpness and slow your page load.
