Free Social Media Tool
Instagram Post Preview Tool
Upload images, videos, or carousel slides and preview how they look in a realistic Instagram-style post mockup before publishing.
Size Guide
Instagram picture sizes for feed posts
Use these sizes when preparing posts, carousels, Stories, and Reels. The preview tool above helps you check how each ratio changes the visible crop.
Square feed post
Reliable for product shots, centered graphics, and profile-grid consistency.
1:1
1080 x 1080 px
Portrait feed post
A strong default because it uses more vertical space in the mobile feed.
4:5
1080 x 1350 px
Landscape feed post
Best for wide scenes, banners, and landscape photography.
1.91:1
1080 x 566 px
Tall photo
Useful for phone-camera photos and supported for single-photo posts and carousels.
3:4
1080 x 1440 px
Stories and Reels
Use a vertical canvas and keep key text away from top and bottom UI areas.
9:16
1080 x 1920 px
How To Use It
Preview the post before the audience sees it
The tool is built for quick creative checks: upload the asset, pick the feed ratio, review the carousel sequence, and export a clean mockup for feedback.
Upload media
Add one image or video for a standard post, or upload multiple files to build a carousel preview.
Test the crop
Switch between square, portrait, landscape, and tall photo ratios to see what gets cropped or letterboxed.
Export the mockup
Adjust the caption, username, and slide order, then export a PNG preview for review or client approval.
Carousel Tips
Keep carousel slides visually consistent
Carousels work best when every slide is designed for the same ratio. Mixed portrait, landscape, and square assets can create unexpected crop changes from slide to slide.
Use 4:5 for feed-first carousels when you want the largest mobile preview.
Keep text and faces away from the outer edges if you plan to use crop mode.
Put the strongest cover image first because it appears in the feed and profile grid.
Preview videos at the exact frame you want before exporting a mockup.

FAQ
Instagram post preview FAQ
Common questions about previewing images, videos, carousels, crop sizes, and mockups.
Can I preview an Instagram carousel post?
Yes. Upload multiple images or videos and the tool will show carousel arrows, dots, slide count, and the same crop setting across the carousel preview.
Does this tool use the Instagram logo?
No. The preview uses a generic Instagram-style post layout, random profile mark, editable username, and familiar feed structure without using Instagram brand marks or implying affiliation.
Can I preview videos?
Yes. Upload a video file and it will render inside the post mockup with native playback controls. The export button captures the current video frame when possible.
What is the best image size for Instagram posts?
For feed posts, 1080 x 1350 px at a 4:5 ratio is a practical default because it fills more mobile screen space. Square posts should be 1080 x 1080 px, landscape posts around 1080 x 566 px, and tall 3:4 photos around 1080 x 1440 px.
Will this publish my post to Instagram?
No. This is a preview and mockup tool only. It helps you check crop, layout, caption, and carousel order before you publish from your own social media workflow.
Are my uploaded files saved?
No. Uploads are previewed locally in your browser and are not sent to a server by this tool.
