How to Use the TikTok Post Preview Tool

Enter your TikTok username and optional display name — both appear in the post overlay exactly as TikTok renders them in the For You feed. Type or paste your caption into the text field: #hashtags are automatically detected and bolded, and the tool tells you in real time when your caption will be truncated behind a "more" tap at approximately 2 lines of visible text. Add the name of the sound or song that will play on your video — it appears in the scrolling music row at the bottom of the phone. Upload your video thumbnail or cover image to fill the 9:16 frame, then choose any applicable content tags (Duet, Stitch, Branded, Live, Ad) to see how they render as overlaid chips on the video. Fill in custom like, comment, save and share counts to simulate engagement and social proof. Toggle the verified badge and spinning music disc on or off, then hit Screenshot to capture the full phone mockup as a PNG — ideal for content planning, client approvals, pitch decks and team reviews.

Everything in This TikTok Post Preview Tool

Built for TikTok creators, brand managers, content agencies, influencer marketers and social media strategists.

Full Phone UI Mockup

Renders a complete TikTok For You feed inside a realistic phone shell — status bar, top navigation, video area with right-side actions, and bottom navigation bar — exactly as viewers see it.

Caption Truncation Preview

TikTok shows roughly 2 lines of caption before hiding the rest behind a "more" tap. This tool warns you when your caption exceeds the visible threshold so you can nail the hook first.

Video Thumbnail Upload

Upload any image as your video cover to see how it fills the full 9:16 TikTok frame. Check text overlays, crop and visual impact before setting the cover inside the TikTok app.

Sound & Music Display

Enter the name of your original sound or licensed track — it renders in the scrolling music strip at the bottom of the video, complete with the musical note icon, just like the real TikTok UI.

Hashtag Highlighting & Content Tags

#Hashtags bold automatically in the caption preview. Toggle Duet, Stitch, Branded Content, Live and Ad tags to see them render as overlay chips on the video — no surprises after publishing.

Full Engagement Simulation

Set custom like, comment, save and share counts across all four action buttons. Numbers auto-format to K and M abbreviations — ideal for client mockups, pitch decks and content previews.

Tips for Creating High-Performing TikTok Videos

1

Hook Viewers in the First 1–2 Seconds

TikTok's algorithm measures completion rate above almost everything else. Your thumbnail and opening frame need to stop the scroll instantly. Upload your cover image here and confirm it grabs attention at the 9:16 frame size before going live.

2

Write Your Hook in the Visible Caption Lines

TikTok collapses captions after roughly 2 lines. Use the truncation preview in this tool to ensure your most compelling sentence — the question, the bold claim, the call to watch — lands before the "more" button cuts it off.

3

Use 3–5 Highly Relevant Hashtags

TikTok uses hashtags to classify your content and surface it to relevant For You feeds. Mix one broad trend tag, one niche community tag, and one or two topic-specific tags. Preview the combination here before your video goes live.

4

Leverage Trending Sounds for Organic Reach

Using a trending sound dramatically increases the likelihood of appearing on the For You page. Enter your chosen track name in the sound field to verify how it displays in the music strip at the bottom of the feed card.

5

Use Duet or Stitch Tags to Ride Existing Virality

Duets and Stitches inherit audience from the source video. Toggle the Duet or Stitch content tag in the previewer to see how the label appears on your video and confirms the format to viewers before the algorithm distributes it.

6

End with a Strong Call to Action for Comments

Comments are one of TikTok's strongest engagement signals. Ask a direct question at the end of your caption or in the last second of your video. Use the caption preview to confirm the CTA is visible in the two-line feed snippet.

Frequently Asked Questions

Is this TikTok post preview tool free?
Yes — completely free with no account required, no watermarks and no usage limits. Open the page, compose your TikTok caption and preview the full phone UI live without signing up for anything.
Does this tool post to TikTok for me?
No. This is a simulation and mockup tool only. It does not connect to the TikTok API. Once your preview looks perfect here, upload your video and caption directly through the TikTok app or TikTok for Business.
How many characters does TikTok show before truncating the caption?
TikTok typically shows around 2 lines of caption text — roughly 80–100 visible characters depending on the device and font size — before hiding the rest behind a "more" tap. This tool warns you when your caption exceeds the visible threshold so you can keep your hook in the first two lines.
What is the TikTok caption character limit?
TikTok allows captions up to 2,200 characters. The progress bar in this tool tracks usage continuously. While 2,200 characters are permitted, captions of 100–150 characters — placing the hook in the first two lines — consistently drive higher engagement because the key message is immediately visible without a tap.
What video dimensions does TikTok recommend?
TikTok recommends 1080×1920 px at a 9:16 aspect ratio for the best full-screen vertical experience. The phone mockup in this tool renders at the correct 9:16 ratio so you can upload your thumbnail and see exactly how it fills the frame before publishing.
Is my caption text or thumbnail stored anywhere?
No. Everything runs entirely inside your browser. Images are processed locally via the FileReader API and rendered directly in the DOM — no text or image data is ever transmitted to any server. Your content stays completely private on your own device.
