Social Media Post Preview
See how your post will look on every platform — before you publish.
This is an unofficial mockup for preview purposes only. Final rendering on each platform may vary.

Schedule on SchedulinPreview your social media posts before you publish
Every platform formats posts differently. The same caption that breathes on Instagram looks cramped on X, and a LinkedIn post that lands in the feed truncates after two lines. Use this preview tool to spot layout issues — overlong captions, truncated headlines, awkward image crops — before you hit publish.
Instagram post mockup
Instagram feed posts use a 1:1 square crop, a gradient ring around the avatar (when posting Stories), and truncate the caption after about 125 characters with a "more" link. The preview above mirrors all three so you can check your hook before posting.
X (Twitter) post preview
X posts cap at 280 characters for free accounts, with URLs counted as 23 characters and most emoji as 2. The preview includes the verified check, like / repost / reply counts, and an attached image when present.
LinkedIn post mockup
LinkedIn truncates posts at around 210 characters in feed before adding a "see more" link. The preview shows that exact truncation point, which is the single biggest factor in whether anyone clicks through to read the rest.
TikTok caption preview
TikTok captions are vertical and overlay the video at the bottom-left. Mobile feed truncates after 3 lines with a "more" tap target. The preview uses a 9:16 frame and the same overlay treatment.
Why preview a post before scheduling?
- Spot truncation early. Most platforms cut off the caption before the limit. The first 1–2 sentences are what matters.
- Catch image-aspect mismatches. A 16:9 photo gets ugly on Instagram. A vertical photo gets squished on X.
- Sanity-check formatting. Hashtags, emoji, line breaks — they all render differently. See it before you post it.
- Share with stakeholders. Screenshot the preview to send to your manager / client for sign-off without scheduling first.
Want to schedule it once you're happy?
Build the post here, then schedule it in Schedulin across Instagram, X, LinkedIn, TikTok, Facebook, Threads, Pinterest, Bluesky and YouTube — from one composer. Use the character counter and engagement rate calculator to optimize before publishing.
Frequently asked questions
Is this post preview tool free?
Yes. Build a preview for any of the supported platforms with no sign-up. Uploaded images stay in your browser — nothing is sent to a server.
Can I download the mockup as an image?
Not in this version — use a screenshot tool to capture the preview. We may add native PNG export later. The preview itself is high-fidelity, so a screenshot lands cleanly in Notion, Slack, or Figma.
Are the mockups accurate?
Close, not pixel-identical. We track each platform's layout — caption truncation points, image crop ratios, action-row icons. Platform redesigns happen often, so treat the preview as a faithful approximation rather than an exact replica.
Why don't I see TikTok exactly like the app?
TikTok's video-overlay UI is the closest the web can get without an actual video. Caption position, action rail, and music banner all match. Final video playback styling won't.
Is this for fake posts / pranks?
We built it for legitimate previews — checking how a post will look before publishing. Don't use the output to impersonate brands or fabricate news; that's a great way to get sued and we'd rather you didn't.
Does it work on mobile?
Yes. The form and preview both adapt to narrow screens. The Instagram, X, and LinkedIn previews are already at mobile-feed width. TikTok is shown in a 9:16 frame.
Why doesn't my image look right on Instagram?
Instagram crops to 1:1 (square) for feed posts. A wide or tall image gets center-cropped. Use our image-sizes guide to see the recommended dimensions for each platform.
Can I use this for stories or carousels?
Not yet. The current version covers feed posts. Stories and carousels are on the roadmap; if you want them sooner, drop a note via the support link in the footer.
