Preview how a caption and image will look before you schedule it on each platform.
This tool renders a realistic mockup of how your caption and image will look once published on Instagram, X, Facebook or LinkedIn, so you can check formatting, image cropping and caption length before you actually schedule or publish the post.
The same caption and image can look very different depending on where it's posted: Instagram emphasizes the image with the caption below it, X keeps everything compact in a single card, Facebook shows the caption above the image, and LinkedIn adds a professional header with your name and title. Checking the mockup for each platform helps you catch an awkward line break or a caption that runs too long before it's live.
Paste your real caption exactly as you plan to publish it, including line breaks and emojis, and upload the actual image or graphic you intend to use so the crop and framing match what you'll see on each platform.
This is a visual mockup for planning purposes only — it does not connect to your social media accounts and cannot actually schedule or publish anything, so you'll still need to copy your final caption into your platform of choice or your scheduling tool.
Social Media Post Scheduler Preview is built for creators, social media managers, small business owners and marketers who need a quick, reliable way to handle one specific job: preview how a caption and image will look before you schedule it on each platform. Instead of digging through a bloated all-in-one dashboard or installing a browser extension, you get a single focused page that does exactly this one thing well, works the same way on desktop and mobile, and keeps your inputs on your own device rather than sending them anywhere else. If this is a task you find yourself repeating every week, bookmark this page so it's one click away next time you need it.
Whatever this tool hands you — text, an image, a calculated number, or a piece of code — treat it as a strong first draft rather than a final answer. Skim the result against the specific post, account or campaign you're working on, adjust anything that doesn't quite match your usual voice or brand, and only then copy it into the platform you're actually posting to. Because everything here runs locally in your browser, you can safely try several combinations of inputs back to back without worrying about rate limits, accounts, or data being logged anywhere — refresh the page any time to start over with a clean slate.
No, it only creates a visual preview in your browser. You still need to copy your caption and image into Instagram, X, Facebook or LinkedIn (or your scheduling tool) to actually publish it.
No, those numbers are placeholder mockup numbers used only to make the preview look realistic. They don't reflect any real engagement.
The current version previews a single image at a time. For a carousel, preview each image individually to check its crop and framing.
No, the image is only read locally in your browser to render the preview and is never uploaded to a server.
