Free LinkedIn Post Preview

By Federico Donatone·Updated October 15, 2026

How to use the LinkedIn post preview

1. Write your post in the box, or paste a draft over the example. Your name, headline and photo can be changed too.
2. Pick Desktop, Tablet or Mobile, and Light or Dark, to see the post the way each reader will.
3. Read the highlighted text in the editor. It is exactly what shows before …more on the device you picked.
4. Select words to make them bold or italic, or select lines to turn them into a list. The smiley button adds emoji where your cursor is, and the spacing button puts one blank line between paragraphs or removes them.
5. Add images, a PDF or a video to see the full post with its media. The files never leave your browser.
6. Click Copy post and paste it into LinkedIn, or copy a share link to send the draft to a colleague for review.

Where LinkedIn cuts your post with …more

LinkedIn does not publish where …more appears. Third-party measurements agree on two limits, and the post is cut at whichever comes first: three lines of text, with blank lines counting as lines, or a number of characters.

Most previewers count characters. This one measures lines. It sets your text in the font LinkedIn uses, at the real width of the feed, finds the last word that fits in three lines next to …more, then applies the character limit. Long words, emoji and blank lines move the cut exactly as they do on LinkedIn.

What the preview shows

• Desktop, tablet and phone layouts, in light and dark mode. Desktop and phone use LinkedIn’s real widths; tablet is an approximation.
• The highlighted part of your draft that people read before they decide to tap …more.
• Images in the same grids the feed uses, from one image to a set with a +N tile, a PDF document with its real pages, and video.
• Hashtags and links in blue, reactions, comments and reposts if you want them, and the time of posting.
• Bold, italic and lists survive when you paste a draft from Google Docs, Notion or a web page, so you do not have to style it again.
• Three checks: the 3,000-character limit, whether your first line survives the phone cut, and how much of the post uses styled letters.

Write the first three lines for the phone

The phone app cuts your post earliest. Write the hook so it reads complete in the first line, keep it short enough to survive the phone limit, and put the proof right after it.

• One idea per line. A sentence that wraps three times on a phone takes the whole preview.
• Remember that a blank line uses one of the three preview lines.
• Bold the hook and nothing else. Styled letters are look-alike symbols that screen readers handle badly.
• Check the phone preview last, after every edit to the opening.

To bold, italicize or list text without the preview, use our LinkedIn text formatter.
