Why previewing your Facebook post matters
A preview brings your copy, page or profile details and media into one feed-style view. Use it to catch awkward spacing, check the balance between text and media, and see where Facebook adds "See more" before anyone else does. The cut moves between desktop, tablet and mobile, so check all three widths.
How Facebook arranges your images
Upload one image or many and the preview arranges them the way the feed does: 1, 2, 3 or 4+ image layouts with a "+N more" overlay. A post can carry up to 10 images, 4 MB each, or a single video up to 4 GB; images and video cannot be mixed in one post.
