Write your post once and see it on X, LinkedIn, Instagram, Facebook, Threads and Bluesky: the character count for each, where “…see more” cuts it off, and how your link card will look. Free, and your text never leaves your browser.
Your post stays in your browser. Only the first link is checked by our server, to draw its preview card.
How your post will look
Previews are close approximations. Each app changes its design now and then, and “…see more” falls in slightly different places on phones and computers.
Character limits for each app
| App | Post limit | Cut off by “see more” |
|---|---|---|
| X (Twitter) | 280 (free accounts) | — |
| 3,000 | After about 210 characters or 3 lines | |
| Instagram caption | 2,200 | After about 125 characters |
| 63,206 | After about 480 characters or 5 lines | |
| Threads | 500 | — |
| Bluesky | 300 | — |
Why does X say my post is too long?
X doesn’t count every character the same. Every link counts as 23 characters, however long it is, and emoji and many non-Latin characters count as 2. That’s why a normal character counter can say 270 while X says you’re over. This tool counts the way X does, and if you’re over, it splits your post into a numbered thread at sentence breaks.
Tips for posts that get read
- Put your hook before “see more”. On LinkedIn that’s the first two lines or so. Most people decide there whether to keep reading.
- Keep hashtags to 3–5 on LinkedIn and X. Instagram allows up to 30.
- Links in Instagram captions aren’t clickable. Put the link in your bio and say “link in bio”.
- Check your link card. If your link shows no picture, use our link preview checker to find out why.
Questions
Do you see what I write?
No. Your post is counted and previewed in your browser, and your draft is saved only on your device. The only thing sent to our server is the first link in your post, so we can draw its preview card.
Are the previews exact?
They’re close approximations. Apps change their designs now and then, and “see more” falls in slightly different places on phones and computers, so leave a little room.
