LinkedIn to X is the compression direction: a post that had 3,000 characters of room must now fit X’s 280-character free tier — roughly a tenth of the canvas — or be rebuilt as a thread. Nothing about the file formats fights you; the work is editorial. The good news is that LinkedIn already made you write the hard part: the line you crafted to survive the “…see more” fold is, at ~140–210 characters, practically a ready-made X post.
This guide maps which pieces of a LinkedIn post survive the cut, what reads wrong pasted into X, and the exact workflow for distilling one platform’s long-form into the other’s short-form — by hand, or composed once in SocialKit with both versions side by side.

Everything that changes between the two composers, side by side.
| Spec | LinkedIn (from) | X (Twitter) (to) |
|---|---|---|
| Primary canvas | 1200 × 1200 px · 1:1 (post) | 1600 × 900 px · 16:9 (post image) |
| Caption limit | 3,000 characters (feed truncates after roughly the first 200) | 280 characters (X Premium subscribers can post up to 25,000) |
| Video length | Native video up to roughly 10–15 minutes depending on where you upload | About 2 minutes 20 seconds for standard accounts; longer uploads are a Premium feature |
| Hashtags | 3–5 professional tags is the convention; more reads spammy | Count toward the character limit; one or two is the platform norm |
| Link cost | URLs count as ordinary characters | Every URL counts as a flat 23 characters (t.co) |
| Long-form route | One 3,000-character post, articles, or document (PDF) posts | Threads, or 25,000-character posts on X Premium |
| Over-limit behavior | Hard cap at 3,000 characters; nothing truncates on display | Over-limit posts are rejected outright, never truncated |

Tip 1
Write the X version first when you can: if the idea cannot survive at 280 characters, the 3,000-character version is probably padded too. Compression is a test, not just a chore.
Tip 2
Mine LinkedIn comments for thread material: the question people asked under your LinkedIn post is often a better X post than the post itself — and it arrives pre-validated.
Tip 3
Don’t screenshot your LinkedIn post: posting it as an image reads as recycled content and locks the text away from X search. Re-typing the idea natively costs two minutes and reads like it belongs.

Usually you don’t — you extract from it. The opener you wrote for LinkedIn’s “…see more” fold (~210 characters desktop, ~140 mobile) is generally the distillation, and it fits 280 nearly as-is. When the supporting points matter, rebuild the post as an X thread with one paragraph per entry instead of trying to shrink everything into a single post.
Free accounts are held to 280 characters per post — over-limit drafts are rejected, not trimmed. X Premium subscribers can post up to 25,000 characters (as of June 2026), shown collapsed in the feed, which suits republishing a LinkedIn post in full. Threads remain the native long-form route on free accounts.
There is no equivalent format. The two working conversions: export the PDF pages as images and attach them four at a time, or turn the document’s one-point-per-page structure into a thread — it maps almost mechanically, since both formats force one idea per unit.
No. The LinkedIn convention of 3–5 professional tags reads spammy on X, where one or two at most — often none — is the norm, and every tag counts toward the 280-character limit. Spend those characters on sharper wording instead.
Compose once, customize the caption per network, and let SocialKit publish to LinkedIn, X (Twitter), and 9 more platforms on schedule — no re-uploading, no copy-paste.
