What can and can't PostSnag capture?

PostSnag captures the public posts on Facebook profiles, Pages, creator accounts, and group members' profiles, along with each post's engagement, timing, caption, and media. It never captures private or friends-only posts, Messenger or direct messages, Stories, or live video, and it never captures anything behind a login you don't have.

What gets captured depends entirely on what's public and what actually loads on your screen as you scroll your own Facebook session.

What PostSnag can capture

• Public posts on profiles, Pages, and creator accounts. Anything you could already see by visiting that profile or Page yourself, PostSnag can capture.

• Posts from members inside a Facebook Group. Captured by opening that member's profile from inside the group, not by scanning the group's main feed directly. See How do Facebook Groups work in PostSnag?.

• Post type, classified as text, photo, video, reel, album, or link. PostSnag looks at the post's actual structure (is there a video, is there more than one image, is there a link preview) rather than guessing from the URL, so the type shown matches what you'd see on Facebook.

• Engagement, including the total reaction count, a breakdown by reaction type (like, love, haha, wow, sad, and angry; Facebook's Care reaction is not tracked separately today), the comment count, the share count, and view counts on videos and reels.

• The exact date and time posted, read from Facebook's own post data where available, or converted from the relative time Facebook shows on screen ("2h," "3d," "Yesterday") when that's all that's available.

• The caption text, preferring the post's own message field.

• Media as thumbnails, including the cover image for a video or reel and up to 20 images from an album.

• The author's public name and profile link, and the original post's URL.

• Basic profile details when you capture a whole profile: display name, avatar, cover image, bio, follower, following, or friend counts, and verification status, wherever Facebook shows them publicly.

What PostSnag cannot capture

• Private or friends-only posts. If you can't already see a post on Facebook with your own account, PostSnag can't see it either. It only reads what your own logged-in session can already load.

• Messenger or direct messages. PostSnag never touches Messenger.

• Stories.

• Live video, while it's actively broadcasting.

• The raw video file. PostSnag saves a video or reel's cover thumbnail and its data (views, caption, date), never the underlying video file itself.

• Non-profile sections of Facebook, like Watch, Marketplace, Events, Notifications, Settings, the top-level Reels tab, Friends, Jobs, and Fundraisers. PostSnag only activates on a profile, Page, or group page.

• Anything on another platform. PostSnag is Facebook-only. See Does PostSnag work on Instagram, TikTok, or other platforms?

• Anything behind a login you don't have. If a profile or group requires membership or a connection you don't have, PostSnag can't see past that any more than you can.

Why some posts don't get captured on the first pass

Capture depends on what actually finishes loading on your screen while you scroll, so a few situations can cause a post to be missed the first time through:

• A fresh page load. The very first post on a profile can appear before PostSnag has fully attached to a freshly opened page. Letting the page finish loading before you scroll helps.

• Media that's still loading. Photos, albums, and video thumbnails load separately from a post's text, and often more slowly, especially on a fast scroll through several albums in a row. Scrolling slowly gives images time to finish loading before PostSnag reads that post.

• A very recent post. Something posted moments ago can still be settling into Facebook's own feed at the exact moment you scan, so it may not fully register until you refresh and scan again.

• Scrolling back upward. Facebook re-renders post cards you've already passed when you scroll back up over them. PostSnag is built to recognize a post it already has, so this doesn't create duplicates, but it also means scrolling up isn't how you catch a missed post; scrolling down through the whole profile again does.

None of this is a bug. It's the normal, expected behavior of capturing content from a live, scrolling page instead of pulling from a fixed archive. Rescanning a profile from the top almost always fills in whatever a first pass missed. See How do I get the most complete and accurate capture? for the full set of best practices.

Edge cases worth knowing

• Reels count as their own post type, but a person's own Reels tab (yourusername/reels) is treated as part of their profile, so reels captured there show up alongside their other posts.

• Shared or tagged content on a profile's own feed gets captured under that profile. If a post appears on a profile's feed because it was shared or someone was tagged in it, PostSnag attributes it to whichever profile page you were actively scanning, which is expected, not a mismatch.

• A person's posts inside a Facebook Group are kept separate from their personal profile posts. Capturing someone's profile from inside a group tags those posts to that group; capturing their own profile page directly captures only their personal posts. See Why are group posts kept separate from personal posts?.

Common questions

Does PostSnag capture the video file itself?
No. PostSnag saves the video's cover thumbnail and its data (views, caption, date posted), never the underlying video file.

Can PostSnag see private or friends-only posts?
No. PostSnag only reads what's already public and visible in your own Facebook session, the same as any visitor to that profile would see.

Does PostSnag capture Facebook Group posts?
Yes, by opening a member's profile from inside the group. Posts captured this way are tagged to that group and kept separate from that person's personal posts.

Why is a post I remember missing after I scrolled past it?
It most likely hadn't finished loading, or its media was still loading, when PostSnag scanned that part of the page. Scroll back over that section or rescan the profile from the top.

Does an exported file include the reaction breakdown, or just the total?
Exported Markdown and CSV files include each post's reaction total. The full like, love, haha, wow, sad, and angry breakdown is visible in the panel and dashboard Analytics, not inside the downloaded file.
