A client-approval mockup
Pasting a 280-character caption and a campaign image produces an Instagram-style mockup card in seconds, ready to screenshot into a client approval message instead of describing the post in words.
Social media post mockup generator
This is the same post-preview engine as our general Social Media Post Preview tool, framed here for anyone searching for a "mockup generator" instead — the underlying widget, truncation logic and platform support are identical, not a separate build. Paste a caption and an optional image URL to see a mockup of the post in Facebook, Instagram, LinkedIn, TikTok, X or YouTube’s own feed card, including where each platform hides the rest of the caption.

How to use the post mockup generator
- Paste your caption. Type or paste your draft caption into the box; nothing you type is uploaded anywhere.
- Add an image URL (optional). Paste a public image URL to see it inside the mockup card, or leave it blank for a caption-only mockup.
- Choose the platform to mock up. Switch tabs to render the same mockup for Facebook, Instagram, LinkedIn, TikTok, X or YouTube.
- Check the truncation line. The mockup greys out the part of the caption that platform hides behind a "more" control.
- Screenshot or copy for approval. Use the rendered mockup to show a client or teammate how a post will look before it is scheduled.
Worked examples
Same mockup, six platforms
One caption pasted once can be mocked up across all 6 supported platforms by switching tabs, rather than rebuilding the mockup by hand for each one.
Post mockup generator FAQ
- Is this a different tool from the post preview?
- No — it is the identical widget and logic as our general Social Media Post Preview tool, just listed here under the "mockup generator" name for that search intent.
- Which platforms can I generate a mockup for?
- Facebook, Instagram, LinkedIn, TikTok, X and YouTube, each rendered with that platform’s own real truncation behavior.
- Can I download the mockup as an image file?
- Not directly — the mockup renders on the page for you to screenshot; there is no built-in image export in this tool.
- Does the mockup generator store or upload my content?
- No, everything renders in your browser from the text and image URL you provide; nothing is uploaded, saved, or sent to a server.
- Is the mockup pixel-identical to the real platform app?
- No, it closely approximates the layout and the real measured truncation point, but font rendering and exact spacing can differ slightly by device and app version.
- Can I use this to preview a post before scheduling it in SkedCast?
- Yes, it is a useful sanity check before scheduling, though it is a standalone preview tool and is not connected to your SkedCast queue or account.
