Common questions

How do I make text bold on LinkedIn?

LinkedIn posts have no formatting buttons, so bold text there is made of Unicode characters that look bold. Type your post above, select the words, click Bold (or press Ctrl+B, Cmd+B on a Mac), then copy the text and paste it into LinkedIn. Click Bold again to undo it.

Does formatted text work in comments, my headline and my About section?

Yes. The characters are plain Unicode, so they paste anywhere LinkedIn takes text, including comments, articles, your headline and your About section, and into most other apps.

Is bold text bad for accessibility or search?

It can be. Screen readers may read Unicode bold letter by letter or skip it, and LinkedIn search may not match those words. Keep it to a few words that need the emphasis, never whole paragraphs, and leave names, hashtags and links plain.

Why do some letters stay plain?

Unicode has bold and italic versions of the English letters A to Z, and bold digits, but none for accented letters, most punctuation or other alphabets. Those stay as they are, so a word like "café" comes out partly bold.

How many characters can a LinkedIn post have?

Up to 3,000. LinkedIn shows about the first three lines in the feed and folds the rest behind "see more", which the preview mimics. Put the hook in those lines. To check one caption against every platform, use the character counter.

How do I add bullet points to a LinkedIn post?

Select the lines and click Bullet list. Each line gets a "•" in front, which LinkedIn keeps when you paste. Click it again to take them off.

Can my posts from other apps go to LinkedIn by themselves?

Yes. Post Once reposts each new post from your Instagram, YouTube, Facebook, Threads or X account to LinkedIn, with its caption, and carousels go up as a swipeable PDF. See cross posting for how it works.

Is my text saved anywhere?

No. The formatter runs in your browser and nothing you write leaves the page.
