Pro Tips

Image Quality

Use high-resolution images (at least 1080px wide). Each platform will display the image differently — Instagram crops to 1:1, Twitter to 16:9.

Caption Length

Instagram allows up to 2,200 characters but truncates at ~125. Twitter limits to 280 characters. LinkedIn truncates at ~200 characters with a “see more” link.

Screenshot Tip

Download previews as PNG images to share with clients, teammates, or for planning content before publishing.

Engagement Numbers

Adjust likes, comments, and shares to mockup how a successful post would look. Great for client presentations and content strategy.

Preview Instagram Posts Before Publishing

Instagram's feed layout has specific rules for how images are cropped, captions are truncated, and engagement is displayed. This tool replicates the exact Instagram feed post format so you can see how your post will look before it goes live.

Upload your image to see how it will appear in the square 1:1 crop format. Write your caption and watch how it truncates after about 125 characters with the familiar “...more” link. Set your display name, verified badge, and engagement numbers to create a realistic preview you can share with clients or teammates.

The preview also includes all four major platforms — switch tabs to see the same content on Twitter/X, Facebook, and LinkedIn. Download any preview as a high-resolution PNG for content calendars, pitch decks, or approval workflows.

Instagram Caption Tips

The first 125 characters of your caption are what users see without tapping “more.” Make those characters count by front-loading your hook or call-to-action. Use line breaks to create visual breathing room. Hashtags can go in a comment instead of the caption to keep things clean.

Instagram allows up to 30 hashtags per post, but research consistently shows that 3-5 highly relevant hashtags outperform large hashtag dumps. The algorithm prioritizes content quality and relevance over hashtag volume.

Frequently Asked Questions

What size does Instagram crop images to?

Instagram feed posts display at 1080x1080 pixels (1:1 square). Portrait posts use 1080x1350 (4:5). This preview shows the square crop view that appears in your profile grid and most feeds.

How many characters can an Instagram caption be?

Instagram allows up to 2,200 characters in a caption, but only the first ~125 characters are visible before the “...more” truncation. Front-load your most important text.

Can I preview Instagram Stories?

This tool focuses on feed post previews. Instagram Stories use a 9:16 vertical format with different overlays. Use our Social Media Image Resizer to get the correct Story dimensions.

Is my image uploaded anywhere?

No. Everything processes in your browser using JavaScript. Your images never leave your device. Close the tab and all data is gone.

Can I download the preview as an image?

Yes. Click “Download Instagram Preview” to save a high-resolution PNG of exactly what the post will look like in the Instagram feed.
