Social Media Post Previewer
Check how your posts look before you publish. Validate character cut-offs, image cropping, and layout for every major platform.
Why you need to preview posts
First impressions on social media are purely visual. If your hook is hidden behind a "See More" button, or your image is cropped poorly, your engagement will suffer.
- Validate the "See More" cut-off point for LinkedIn.
- Check how Instagram crops your 4:5 images in the feed.
- Ensure your TikTok caption doesn't cover vital video content.
The "Safe Zone" Rule
On platforms like TikTok and Reels, the UI (username, music tag, like buttons) covers a large part of the screen. Our previewer helps you stay in the "Safe Zone" so your content is always readable.

Post Previewer FAQ
Why should I preview posts before publishing?
Previewing catches formatting errors, awkward character cut-offs, and poor image cropping before your audience sees them. That saves you deleting and reposting, and protects the first impression.
Which platforms can I preview?
You can preview posts for Instagram (feed), TikTok (video overlay), LinkedIn (feed), and X (tweet). Each mockup replicates the exact layout, fonts, and UI elements of the platform.
Does the previewer show the 'See More' cut-off?
Yes. For Instagram and LinkedIn, the preview shows exactly where your caption gets truncated and the 'See More' or '...more' button appears, so you can front-load your most important message.
Can I preview video content?
You can upload a video thumbnail or frame to see how it will look in the feed. For TikTok, the previewer shows how your caption and hashtags overlay on the video screen.
Is my content stored or shared?
No. All content is processed locally in your browser. Your text and images are never uploaded to our servers or stored anywhere.
How accurate is the TikTok preview?
The TikTok preview shows the standard UI overlay including username, caption area, and action buttons. This helps you identify if important visual content will be hidden behind interface elements.
Can I use this tool for Instagram Reels or Stories?
The current preview is optimized for feed posts. For Reels and Stories, the aspect ratios differ (9:16 vertical), but you can still check how your caption text and hashtags will appear.
