Bulk Delete Posts Using Facebook in a Web Browser
The first step to deleting your old Facebook posts is to select the posts you no longer want (up to 50 at a time). There are a couple of ways to do that, including filtering posts if you want to delete something specific.
How to Manage Your Posts in the Facebook App
In the Manage section of Facebook settings, you can delete, archive, or restore content. This feature is currently only available on the Facebook mobile app.
Can’t Delete Some Posts?
You might notice that when you try to delete some posts, the deletion option is grayed out, and you can only select the hide option. This might occur for specific posts like profile picture updates, posts that weren’t created by you, or posts with particular privacy settings. For posts you’re unable to delete using the manage posts option, you can delete those posts individually. Find the posts on your Timeline, select the three dots in the upper-right corner of the individual post, and select Delete.
