Instagram Post Preview

Upload your image or video here, choose the format and add your caption. The preview shows the post inside a phone screen with Instagram's interface on top, so you can see the crop, the caption cut-off and the profile grid thumbnail before you publish.

Feed photos can be square (1080 x 1080), portrait (1080 x 1350, 4:5) or landscape (1080 x 566, 1.91:1). Stories and Reels are vertical 9:16, ideally 1080 x 1920. Images outside the feed range are cropped to the nearest supported ratio, which the preview shows when you pick Auto.

On Stories, the progress bar and account name sit at the top and the reply bar at the bottom. On Reels, the caption, username, audio and buttons cover the bottom and right side. A common rule from Meta's ad guidance is to keep text and logos out of the top 14% and the bottom 35% of a Reel. Turn on safe zones to see these areas.

Instagram's profile grid now shows 3:4 thumbnails. A square post loses a strip on the left and right, and a vertical Reel shows only its middle section. The grid preview shows the crop so you can move text or faces away from the edges.

Yes. Instagram crops every slide in a carousel to the ratio of the first one. If your first image is square, portrait slides after it are cropped to square too. Put a portrait image first if you want the whole carousel to take up more of the screen.

No. The preview runs entirely in your browser. Files are read locally and never sent to a server, and they disappear when you close the page.

The first line is all most people see before “more”, so use it for the hook or the call to action. A line like “Comment GUIDE and I'll send it to you” works well with Hypello, which sends the DM automatically to everyone who comments the keyword.
