Build a full Instagram-style post screenshot — profile, photo size, caption, likes, and a few visible comments — then download a PNG. These are made-up previews only; nothing is published to Instagram.
Instagram post sizes
Choose the size in the tool before you finish the caption — the crop changes how the post looks in a slide.
| Type | Ratio | Recommended size |
|---|---|---|
| Portrait | 4:5 | 1080 x 1350 |
| Square | 1:1 | 1080 x 1080 |
| Landscape | 1.91:1 | 1080 x 566 |
When to use Portrait
Best for modern feed previews, creator posts, product shots, and mockups where the image should take more vertical space.
When to use Square
A safe choice for simple Instagram post mockups, campaign drafts, portfolio examples, and older feed-style screenshots.
When to use Landscape
Useful for wide visuals, event banners, editorial previews, and presentation mockups that need a horizontal image.
Start from ratio, then fill the post
Portrait (4:5), square (1:1), and landscape (about 1.91:1) change how the mockup looks in a slide. Choose the size before you finish the caption so the crop matches the story. Templates can load a campaign-style example you then rewrite.
A full post preview, not only the photo
Many Instagram post makers help you design the image you might upload later. This tool puts your image inside a post layout: username, verified badge, location, caption, liked-by line, counts, timestamp, and a few visible comments. Use it when you need the whole post screenshot, not just the graphic.
Full post vs comments-only page
Stay here when the photo, caption, and likes should appear together. Open the Instagram Comment Generator when you care about the comment thread itself, or when you only need Comment Ideas text. For comments under a short video, use the TikTok Comment Generator.
Create an Instagram Post Mockup in Seconds
Start from a template or a blank post, add profile and photo, set likes and two or three comments under the caption, then download. Useful for campaign reviews, pitch decks, content calendars, and class demos — always as fiction, never as proof of a live post.

How to create an Instagram post mockup
- Set profile and post size. Add profile photo, username, location, and verified badge, then choose Portrait, Square, or Landscape before you write the final caption.
- Add the photo and caption. Upload the post image and write the caption that should appear on the post preview.
- Set likes and the comments that show. Edit like count, liked-by name, comment count, timestamp, and the few comments under the post. Longer reply threads belong on the Instagram Comment Generator.
- Download the post screenshot. Download a PNG or copy the image if your browser supports it. Uploads stay on your device; nothing is sent to Instagram or Meta.

FAQ
What is an Instagram post generator?
A mockup tool that builds a full Instagram-style post screenshot around your image — profile, caption, likes, timestamp, and a few visible comments. It is not an official Meta product and does not publish posts.
Is the export a real Instagram post?
No. The PNG is a fictional preview for decks, planning, education, and design. It is not live, not official Instagram software, and not proof of a published post.
Which post sizes can I choose?
Portrait 4:5 (1080×1350), square 1:1 (1080×1080), and landscape about 1.91:1 (1080×566). Pick the ratio before you finalize caption length so the crop matches the story.
How is this different from an Instagram post maker?
A post maker usually designs the graphic you might upload later. This page adds the full post layout around that graphic so you get a complete post screenshot.
How many comments show on the post?
A few comments under the caption — enough to look natural on a post preview. Longer reply threads belong on the Instagram Comment Generator.
When should I use the comment generator instead?
Open Instagram Comment when the thread is the subject, or when you only need Comment Ideas text. Stay here when photo, caption, and like row must appear together.
