Social media post preview

Social & copy

See how your post could look on LinkedIn, X, Instagram and Facebook before you publish.

Type your post text to see it on LinkedIn, X, Instagram and Facebook.

How it works

Preview one post as a LinkedIn, X, Instagram and Facebook mockup, check documented character limits and save a PNG. Free, nothing uploaded.

  1. Type your name, handle and post text, and add a picture or link if you want.
  2. Compare the four previews, and fix anything over a documented limit.
  3. Select the preview you want and save it as a PNG.

Questions

Is my text or picture uploaded?

No. Everything is drawn in your browser and nothing is sent anywhere. A link is shown as plain text and is never opened.

Are these exact copies of each network?

No. They are neutral approximations of layout, text wrapping and spacing in our own style. The real feed may differ, and networks change their designs.

Why is my text not cut with "see more"?

We cut text only where the network documents the cut-off on an official page. For these four networks we found none, so the full text is shown.

Where do the character limits come from?

From each network's official pages, checked on 2026-11-06: LinkedIn posts hold up to 3,000 characters, and X posts up to 280, with links counted as 23. We found no official page for Instagram or Facebook, so no warning is shown for them.

How is the PNG made?

The selected preview is rendered to an image on your device at twice the screen resolution, so it stays sharp when shared.
