Limit past posts is a Facebook setting that changes every past post on your profile that's visible to more than your friends, such as Public posts, to Friends only, all at once. It's under Settings and privacy, Settings, Posts, and as of November 2026 it can't be reversed in one click: putting old audiences back means editing each post by hand.
It's one of the quickest privacy clean-ups on Facebook, and one of the bluntest. Before you press it, it helps to know exactly which posts it touches, which it ignores, and what you'd be giving up.
What the setting does in plain words
Every post you share on your profile has an audience, picked with the audience selector: Public, Friends, Only me or a custom group. Over the years that adds up to a long trail of posts, some of them public. Limit past posts takes everything in that trail that more people than your friends can see and switches it to Friends in one action. It doesn't delete anything and it doesn't change who your friends are. It narrows the audience.
How to find Limit past posts
These are the computer steps from the Facebook Help Centre, with the menu names as of November 2026:
- Click your profile picture in the top right of Facebook.
- Select Settings and privacy, then click Settings.
- On the left, click Posts.
- Next to Limit who can see past posts, click Limit past posts.
- Click Limit past posts again to confirm.
That second click is the last chance to stop. The Help Centre also has tabs for the Android app, the iPhone and iPad apps, Facebook Lite and the mobile browser, so on a phone the same setting sits under Settings and privacy, though labels can move around between versions.
What it changes and what it leaves alone
This is where most of the surprises come from. The setting only works on posts you've shared yourself, with an audience bigger than Friends. Here's how that plays out:
| Kind of post | Does Limit past posts change it? | What to know |
|---|---|---|
| Your old Public posts | Yes | They become Friends only. |
| Posts shared with a custom audience | No | Audiences such as Friends except acquaintances or Close Friends stay as they were. |
| Posts where you tagged someone | Partly | The audience still includes the person you tagged and the people they include in posts they're tagged in. |
| Someone else's post you're tagged in | No | The person who posted it controls its audience. |
| Posts you made on someone else's profile | No | That person controls who sees them. |
| Posts or comments in a public group | No | The Help Centre says these are always public and can be seen by anyone. |
| Reels and stories | Set separately | You choose their audience separately, so check those settings on their own. |
For stories in particular, my guide to Facebook story privacy walks through those separate settings. If you tagged someone in an old post and want it tighter, the Help Centre's suggestion is to change that post to friends only or to remove the tag.
Why there's no one-click undo
Meta is direct about this: limiting the audience of your previous posts can't be reversed in one click. If you change your mind, you'll need to change the audience of each individual post back to what it was. On a profile with years of public posts, that's a long afternoon, and you may not remember which posts were public in the first place.
That's the reason to treat it as a one-way door. Going back means scrolling, opening the audience selector on each post and picking Public again.
Fixing one post instead
If only a handful of posts bother you, change them one at a time and leave the rest alone:
- Click your profile picture in the top right of Facebook, then click your name to go to your profile.
- Scroll down to the post you want to edit.
- Click the audience selector next to the date or time on the post. The icon looks different depending on its current audience.
- Choose who can see it, for example Public, Friends or Only me.
A few things to know when you do it this way. Changing one post's audience only changes that post; the next time you post, the audience goes back to your default. The change shows up on every device, so a fix on your computer also applies in the app. And if you've chosen to lock your profile, your sharing choices are more restricted.

Posts other people put on your profile
Limit past posts only controls posts you've shared. Things friends post on your profile have their own setting: Settings, then Profile and tagging, then Who can see what others post on your profile, where you pick an audience and click Done. The Help Centre adds that posts on your profile may still appear in Feed and search for the people in the audience they're shared with. If you'd rather stop people posting there at all, here's how to stop people posting on your profile.
Business Pages and second profiles
If you run a business Page, this setting isn't the tool for it. The Help Centre says default audience settings for Page posts are different from those for profile posts, and Limit past posts sits in your profile's settings. Your Page's public posts aren't what this button is for.

The same goes for second profiles. If you have more than one Facebook profile, the audience you choose on one doesn't carry over to the others, so you'd need to run Limit past posts from each profile you want cleaned up.
What I'd do before pressing the button
I'd use Limit past posts before a job search, a career change or a rebrand, when old public posts from years ago don't match who you are now and you don't want strangers scrolling back through them. It's fast, and for most personal profiles it does what you want.
I'd skip it if any of your old Public posts are still doing work for the business: a post people share to find you, a launch announcement you point clients to, or anything you've linked from elsewhere. Once it's limited, it stops being public, and you'd have to find and reopen each one by hand.
Before you press it, I'd go to your activity log, which the Help Centre names as the place to review your posts and the things you've been tagged in. Note the few public posts you want to keep public, run the setting, then switch just those back one at a time. That's a short list to fix instead of a long one.
