Add bold, italic, strikethrough, underline, and special characters to your LinkedIn posts. This free tool converts your text to Unicode characters that render as formatted text on LinkedIn.
LinkedIn's native editor does not support bold, italic, or any text formatting in posts and comments. Every post looks the same: plain text in the same font and size. This means that well-formatted posts immediately stand out in the feed because they break the visual pattern that people are used to scrolling past.
Formatted text helps you emphasize key points, create visual hierarchy, and make your posts more scannable. When someone is scrolling through dozens of posts, bold headers and bullet points catch the eye far more effectively than a solid block of unformatted text. The result is higher engagement: more people stop scrolling, read your post, and interact with it.
This tool works by converting your text to Unicode characters that look like bold, italic, or other formatted styles. These are actual Unicode characters (not HTML or markdown), so they display correctly on LinkedIn, in comments, in messages, and on mobile devices without any special rendering needed.
LinkedIn does not have a built-in bold button for posts. To bold text, you need to use Unicode Mathematical Bold characters, which are a separate set of characters in the Unicode standard that look visually identical to bold versions of regular letters. This tool converts your text to these characters automatically.
To use it: type or paste your text in the input field on the left, select the text you want to format (or leave it to format everything), and click the Bold button. The formatted text appears in the output field on the right. Click 'Copy to clipboard' and paste it directly into your LinkedIn post or comment.
The bold Unicode characters work everywhere that supports Unicode text, which includes LinkedIn posts, comments, messages, and even your headline and summary sections. They also work on other platforms like Twitter/X, Facebook, and Instagram bios.
Beyond bold, this tool supports several other formatting styles. Italic uses Unicode Mathematical Italic characters for emphasis and is great for quotes, book titles, or adding subtle stress to a word. Bold Italic combines both styles for maximum emphasis.
Strikethrough adds a line through your text using combining Unicode characters (U+0336). It is commonly used for humor, corrections, or showing something that has been crossed out. Underline works similarly using combining character U+0332 to add a line beneath each character.
The tool also includes special insert buttons for bullet points (•, ‣, ◦), arrows (→, ➜, ▸), and separators (horizontal lines) that help you structure longer posts. An emoji grid provides quick access to the most commonly used LinkedIn emojis like checkmarks, rockets, and fire symbols.
LinkedIn imposes different character limits depending on where you are writing. Regular posts allow up to 3,000 characters, which is enough for a substantial thought-leadership piece. Comments are limited to 2,600 characters. Your profile headline allows 220 characters, and the About section supports up to 2,600 characters.
The character counter in this tool shows your current count against these limits so you know exactly how much space you have left. Keep in mind that Unicode formatted characters count the same as regular characters toward these limits, so formatting does not cost you extra space.
For best results, aim for posts between 800 and 1,500 characters. Posts in this range tend to get the most engagement on LinkedIn because they are long enough to provide value but short enough that people actually read the whole thing. Use the character counter to stay within this sweet spot.
Start with a strong opening line. LinkedIn truncates posts after about 140 characters with a 'see more' link, so your first sentence needs to hook the reader. Use bold for this opening line to make it stand out even more.
Break your post into short paragraphs with blank lines between them. Walls of text perform poorly on LinkedIn because they are hard to read on mobile screens, where most LinkedIn consumption happens. Use bullet points for lists, and add spacing between sections.
Use formatting sparingly. A post where every other word is bold loses its impact. Reserve bold for headers and key takeaways, italic for emphasis or quotes, and special characters like arrows and bullets for lists. The goal is readability, not decoration.

No. LinkedIn's post editor does not have formatting buttons for bold, italic, or other styles. This tool uses Unicode characters that visually appear as formatted text. These characters are part of the Unicode standard and display correctly on all devices and platforms.
Yes. Unicode characters render consistently across all devices and operating systems. The bold, italic, and other formatted characters will look the same whether someone views your post on an iPhone, Android phone, Windows PC, or Mac.
There is no evidence that LinkedIn penalizes posts using Unicode formatting. However, excessive or gimmicky use of special characters may reduce readability, which could indirectly affect engagement. Use formatting to improve clarity, not as decoration.
Yes. Unicode formatted text works in LinkedIn posts, comments, direct messages, your headline, and your About section. It works anywhere that LinkedIn accepts text input.
LinkedIn posts have a 3,000 character limit. Comments allow up to 2,600 characters. Your profile headline supports 220 characters, and the About section allows 2,600 characters. Unicode formatted characters count the same as regular characters toward these limits.
