How to add photos to fb albums without posting it?

To add photos to Facebook albums without posting them, first, create or select the album you want to add to. Click on "Add Photos" or "Upload Photos" and choose the images from your device. Before saving, make sure to adjust the album's privacy settings to "Only Me" to prevent others from seeing the photos. Once you've uploaded the photos, they will be stored in the album but remain hidden from your timeline and newsfeed.
