A TikTok post preview tool shows your creative in the full-screen 9:16 feed with the username, caption and right-hand action buttons overlaid, so you can see which parts of your design are covered by TikTok’s interface before you publish.
TikTok covers a serious amount of your frame. The username and caption sit along the bottom, the follow, like, comment, save and share buttons run up the right edge, and the whole thing is full-screen so nothing is letterboxed out of harm’s way. Text you burned into the lower third of your creative will be hidden. A preview shows the overlay in place so you can move it.
Upload the image or video frame you plan to post, add your caption and business name, then select the TikTok tab. The preview renders full-screen with the interface overlay, so you can immediately see whether anything important is buried behind it.
| Aspect ratio | 9:16 vertical (1080 × 1920 px) |
|---|---|
| Caption limit | 2,200 characters |
| Caption visible in feed | Around 100 characters before "more" |
| Right-side UI overlay | Approximately 140 px from the right edge |
| Bottom UI overlay | Approximately 480 px of the lower frame |
| Profile picture | 200 × 200 px |
TikTok captions can be up to 2,200 characters, but only around the first 100 characters show in the feed before a "more" link. Keep the hook at the very front.
Safe zones are the parts of the 1080 × 1920 frame not covered by TikTok’s interface. Keep key text and logos clear of roughly 140 px on the right edge and around 480 px at the bottom, where the action buttons and caption sit.
The tool previews a still frame in the TikTok feed layout. Export a key frame from your video and upload it to check the caption placement, safe zones and overall composition.
No. Your image and caption stay in your browser while you build the preview and nothing is posted to any social network. A preview is only stored on our servers if you click Share, which creates a private link you can send to a client or teammate.
Yes. The social media post preview tool is free and requires no account, no credit card and no sign-up. Nothing you upload is published anywhere. Content Manager is the paid product behind it — a social media management platform for agencies — but the preview tool works on its own.
This preview tool is a free standalone feature of Content Manager — an AI-powered platform built for marketing agencies. With a full account you can generate brand-trained captions using AI, schedule posts across every platform, manage multiple clients from a shared workspace, and get content approved through a built-in client portal. No more copy-pasting between tools.
