Social Media Post Preview Tool
Type your caption, optionally add an image URL, and see a live mock-up of how your post will read on three major platform layouts before you publish anywhere.
How to Use the Post Preview Tool
- Enter the display name you post under.
- Type or paste your caption into the text box.
- Optionally paste a direct image URL to see it inside the preview cards.
- Compare how the same caption reads across the Instagram-style, Facebook-style and X-style layouts, then adjust wording or length as needed.
Why Use This Tool?
Why does the same caption look different on each platform?
Each platform truncates captions at a different length, wraps text differently, and displays images at different aspect ratios. A caption that reads perfectly on Instagram's square-friendly layout might get cut off with a "See more" link on a Facebook feed, or feel unusually long on X's more compact timeline. Previewing all three side by side helps you catch these differences before you post the exact same text everywhere.
Are these real platform embeds?
No — these are generic mock-up cards built with this site's own styling, loosely resembling the layout conventions of Instagram, Facebook and X (name, avatar circle, caption, optional image). They are designed purely to help you judge caption length, line breaks and image framing, not to pixel-match any platform's exact current design.
Is this tool affiliated with Instagram, Facebook or X?
No. Multi Tools Farhad is not affiliated with, endorsed by, or sponsored by Meta Platforms, Inc. or X Corp. Platform names are used only to describe the general style of layout being previewed.
Is my caption or image data uploaded anywhere?
No. Everything renders instantly in your browser using JavaScript. Your text is never sent to a server, and an image URL is only loaded directly by your browser for display — nothing is stored or logged. No signup is required.
