Post Formatter is a free browser extension and set of online tools for adding text formatting to social platforms that only accept plain text. It converts text into Unicode characters that render as bold, italic, strikethrough, underline, and 20+ font styles, so the formatting displays correctly on LinkedIn, X (Twitter), Facebook, Threads, Bluesky, YouTube, and Pinterest.
The extension formats text inline as you write, with keyboard shortcuts, a live post preview, Smart Paste from Google Docs / Word / Notion, draft management, a character counter, and optional AI proofreading and auto-styling (with your own OpenRouter API key).
A startup from Vilnius, Lithuania that is founded by Artyom Shimanski.

Easy to use
Post Formatter offers a simple and intuitive interface that allows users to quickly format their text for various social media platforms without requiring technical skills.
Multi-platform support
The tool supports formatting for multiple social media platforms such as LinkedIn, Facebook, Twitter, and others, making it a versatile option for content creators managing multiple accounts.
Free to use
Post Formatter is available as a free online tool, making it accessible to anyone who needs to format their social media posts without incurring additional costs.
Real-time preview
Users can see a real-time preview of how their formatted text will appear, allowing them to make adjustments before publishing to ensure the post looks exactly as intended.
Text styling options
The tool provides various text styling options including bold, italic, and special Unicode characters that can help posts stand out in social media feeds where native formatting options are limited.
You format inline instead of copy-pasting, it works across seven platforms (not just LinkedIn), and it adds 20+ font styles. AI proofreading and auto-styling run on your own OpenRouter API key, so you control both cost and data.
LinkedIn creators, founders, marketers, recruiters, job seekers and social-selling professionals who want their posts to stand out in the feed - anyone who writes regularly on LinkedIn or other text-only social platforms and wants bold headlines, cleaner structure, and a quick preview before publishing
A Chrome Extension (Manifest V3) written in TypeScript and React, with its UI rendered in a Shadow DOM so it doesn't clash with host-page styles. Text styling uses Unicode Mathematical Alphanumeric Symbols rather than HTML/CSS. Optional AI features call the OpenRouter API. The companion site (postformatter.com) is built with Astro, React and Tailwind CSS, hosted on Cloudflare Pages.
Post Formatter styles text inline, directly inside the LinkedIn, X, Facebook, Threads and Bluesky post box - you select your text and format it without copy-pasting from a separate website. It uses real Unicode characters (from the Mathematical Alphanumeric Symbols block), so bold, italic and 20+ other styles display correctly for every reader on any device. It also bundles the whole workflow in one place: live post preview, Smart Paste from Google Docs, a character counter, drafts, and optional AI proofreading
LinkedIn's post composer only accepts plain text, so there's no built-in way to bold a headline or italicize a key phrase. Post Formatter was built to close that gap in a single free tool - inline Unicode formatting plus the surrounding workflow (preview, drafts, character counting) that creators were otherwise piecing together from several separate sites.
Post Formatter appears to be a useful, lightweight tool for quickly formatting and cleaning up text for social media and blog posts, making it a solid choice for users who need fast, no-frills formatting without learning complex software.
