About

Co-formatter — Built-in Formatting for LinkedIn (Bold, Italic, Underline & Lists)

Make your LinkedIn posts and comments stand out. Co-formatter adds a clean, native-looking formatting toolbar right inside LinkedIn's post editor and comment boxes — so you can write bold, italic, underline, strikethrough, monospace, and bullet or numbered lists in seconds. No copy-paste from another website. No sign-up. No cost.

LinkedIn doesn't let you format text. Co-formatter does — instantly, where you already write.

✦ WHY CO-FORMATTER?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Plain LinkedIn posts scroll right past readers. Formatted posts get noticed. Bold hooks, italic emphasis, and clean bullet lists make your writing easier to read and far more likely to stop the scroll, earn likes, and grow your reach.

Most "LinkedIn text formatter" tools force you to leave LinkedIn, type in a separate website, then copy and paste the result back. Co-formatter skips all of that. It lives inside LinkedIn, so you just select your text and click — the formatting appears right in the editor, exactly like a built-in feature.

1. Click "Start a post" or open a comment box on LinkedIn.
2. Select the text you want to format.

✦ PRIVACY FIRST
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Co-formatter runs entirely in your browser. It does not collect, store, or transmit any of your data. There are no accounts, no tracking, and no network requests — your text never leaves the page. The extension only runs on LinkedIn.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✦ GOOD TO KNOW
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
LinkedIn stores posts as plain text, so "bold" and "italic" are created using special Unicode characters that look like styled letters. This is the same technique every LinkedIn formatting tool uses, and it works across desktop and mobile feeds. Because these are stylized characters, use them for emphasis and headings rather than entire paragraphs for the best readability and accessibility.
