Instagram post mockup generator
The short answer
This generator places your image inside a neutral post frame — avatar, name row and action row — so you can show a client or a teammate how a post will read, and exports the whole mockup as a PNG — checked 29 October 2026.

Instagram’s Help Center says photos are shared at up to 1080 px wide, and Meta’s developer documentation accepts feed images from 4:5 to 1.91:1, so 1080 × 1080 is the full-resolution square. Instagram moved the profile grid from squares to 3:4 tiles in January 2025 without publishing a tile size; the centred 3:4 crop shown here is the default before you adjust the grid preview.

Add the image you want to frame
Drag a file here, paste from the clipboard, or choose one below. PNG, JPEG, WebP and still HEIC photos.
Nothing is uploaded. The file is read by this tab only.
Runs on your device. Your image is decoded, cropped and encoded by this browser tab. It is never uploaded, and there is no image-processing service behind this page.
Why this asset is awkward
Showing a bare 1080 × 1080 export to someone who is not a designer rarely lands. Put the same image inside a post frame with an avatar and an action row and the composition suddenly makes sense, because that is the context it will be seen in.
The frames here are deliberately generic: plain shapes, no platform logos, no reproduced interface artwork. They exist to communicate scale and crop, not to imitate Instagram. You can set a display name and caption, switch between light and dark, and export the framed mockup as a PNG.
Exact specification
| Asset | Pixels | Ratio | Formats | File limit |
|---|---|---|---|---|
| Instagram post (square) | 1080 × 1080 | 1:1 | png, jpeg | Not published |
| Instagram post (portrait) | 1080 × 1350 | 4:5 | png, jpeg | Not published |
| Instagram Story | 1080 × 1920 | 9:16 | png, jpeg | Not published |
What the overlays mean
The image area inside the frame is the true crop — everything you see there is what actually gets posted. The surrounding chrome is a neutral illustration of context and is never part of the exported asset unless you choose the mockup export.
- Profile grid crop (3:4): keep content here, Post 1:1
- Since early 2025 the profile grid shows 3:4 tiles, so a square post loses a strip from each side there. The feed still shows the whole square.
- Profile grid crop (3:4): keep content here, Post 4:5
- The profile grid shows 3:4 tiles, so a 4:5 post loses a thin strip (about 34 px) from each side there. The feed still shows the whole post.
- Story text safe area: keep content here, Story
- Meta recommends keeping text and logos out of roughly the top 250 px and bottom 250 px of a 1080 × 1920 Story, where the profile row, timer and reply bar sit.
- Reply bar: covered, Story
- The bottom strip carries the reply field and share actions.
Three things that go wrong
- 01
Use it for approval, not for publishing
Export the clean asset for Instagram and the framed mockup for the deck. Posting a mockup by accident is an easy mistake to make.
- 02
Dark mode changes everything
A design with a white background floats on a light frame and becomes a glowing rectangle on a dark one. Check both before you sign it off.
- 03
Keep the caption honest
A three-word caption in the mockup and a four-line caption in reality is how designs get approved and then break.
Questions people actually ask
Is this an official Instagram mockup?
No. The frames are neutral, generic shapes drawn by this tool. They contain no Instagram logos, no reproduced interface elements and no branding, and this site is not affiliated with Instagram or Meta.
Can I export the mockup itself?
Yes — you get two exports. The clean asset is the image alone at full resolution, for posting. The mockup export is the framed version as a PNG, for presentations.
Does it work for Stories as well as posts?
Yes. Switch the canvas to 1080 × 1920 and the frame becomes a full-screen Story frame with the top and bottom interface strips indicated.
