How to Use the Twitter / X Post Preview Tool
Getting started takes under a minute. Enter your display name and @handle in the fields provided, then type or paste your tweet into the content box — the live mockup on the right updates with every keystroke. Hashtags and @mentions are automatically highlighted in X blue, exactly as they appear in the real timeline. Use the 280-character ring counter to ensure you stay within the limit. Upload a photo or graphic to see how it renders inside the tweet card, and fill in custom like, repost, reply and view counts to simulate social proof. Toggle verified badge on or off, switch to dark mode to preview how your tweet looks for users who prefer the dark timeline, and enable Thread Mode to compose a two-tweet thread. When your post looks perfect, hit Screenshot to download a shareable PNG — ideal for content calendars, client sign-offs or design reviews.
Everything in This Twitter X Post Preview Tool
Built for social media managers, marketers, journalists, creators and agencies.
Real-time Timeline Mockup
Every keystroke instantly updates a pixel-accurate Twitter/X post card, so you see the final result before you publish a single word.
280-Character Ring Counter
A live ring indicator shrinks as you type and turns amber then red as you approach and exceed the 280-character tweet limit.
Image Attachment Preview
Upload any JPG, PNG, GIF or WebP file to see how it scales inside the tweet card's rounded image container — no surprises after posting.
Hashtag & Mention Highlighting
#Hashtags and @mentions are automatically detected and rendered in X blue — just as the real Twitter algorithm displays them.
Thread Mode
Enable thread mode to compose a two-tweet thread and preview how the second reply looks attached below the original post with a connecting line.
Dark & Light Mode Preview
Switch between light and dark timeline themes with a single click — because a significant share of X users have dark mode enabled.
Tips for Writing High-Performing Tweets & X Posts
Front-load Your Most Valuable Idea
Twitter/X users make a split-second decision to read or scroll. Use the preview to confirm your strongest sentence or hook is visible in the first line — before any line break or image.
Respect the 280-Character Limit
Watch the ring counter in real time. Tweets that use 70–120 characters tend to earn higher engagement because they're punchy and easy to retweet without editing. Check it here first.
Use 1–2 Relevant Hashtags (Not More)
Research shows tweets with one or two hashtags get roughly double the engagement of those with none — but engagement drops sharply above two. Verify hashtag highlighting in the preview.
Images Drive More Clicks
Tweets with images receive up to 3× more engagement than text-only posts. Upload your visual to the previewer and confirm the crop looks right before posting to the live timeline.
Use Threads for Long-form Thinking
When a single tweet isn't enough, threads dramatically outperform standalone posts for reach. Enable Thread Mode in this tool to see exactly how your first and second tweets connect visually.
Preview in Dark Mode Before Posting
Over 80% of Twitter/X users enable dark mode on mobile. Toggle the dark preview here to ensure your image, text and any overlaid copy remain legible against the dark timeline background.
