    Thread generators

    Pick a platform. Each generator uses that platform's limit, and you can change it.

    Reddit post formatter

    Not a thread tool: Markdown editor with preview, up to 40,000 characters per post.

    What makes the tools different

    • Counts the way X counts

      Links count as 23 and emoji and Chinese, Japanese and Korean characters count as 2, so the number you see matches what X is likely to show.

    • Format a selection, not just the whole text

      Select a few words and make only those bold or italic, then copy the post.

    • Preview before you post

      See an approximate preview of a shared link, a Reddit post or a WhatsApp message before anyone else does.

    • Safe link checks

      The link previewer fetches the page through our server, refuses private and local network addresses, and does not store the URL.

    • Split images for grids and prints

      Cut one picture into grid tiles, carousel slides, equal strips or printable pages.

    • Build Google Ads responsive search ads

      Draft headlines and descriptions within Google's limits, check them, preview the ad and export a CSV.

    How Threadify works

    1. Paste your text

      Paste a draft, article or notes into a thread generator, or start from a template.

    2. Split within the limit

      Text is split at paragraph and sentence breaks, then at words when a sentence is too long, and every post stays within the limit. You can force a break with --- on its own line.

    3. Copy and post

      Copy each post or the whole thread, or download it as a .txt file, then paste it into the app.

    Free social media thread generator and formatting tools

    Threadify is a set of free tools for writing and preparing social media posts. The Twitter thread generator splits long text into numbered posts that fit the 280 character limit, counted the way X counts. The Threads thread generator, LinkedIn post generator and Mastodon thread generator do the same for their own limits. Reddit works differently: the Reddit post formatter is a Markdown editor with a live preview, and the Reddit post preview shows how a post may look in the feed.

    Text formatters add bold, italic and other styles for Instagram text, LinkedIn posts and tweets using Unicode letters, while the WhatsApp text formatter and Telegram text formatter use each app's own formatting marks. Character counters show live counts for tweets, Instagram captions and LinkedIn posts.

    For images, you can resize an image for Instagram posts, stories and reels, cut a picture into grid tiles with the Instagram photo splitter, or use the image splitter for prints and puzzles. The Instagram feed planner and TikTok feed planner let you arrange a grid before you post.

    Marketing tools include a UTM builder for campaign links, a QR code generator and a link previewer that shows how a URL may look when shared. The Google Ads headline generator helps you draft responsive search ads within Google's limits. The fake tweet generator makes labelled mock tweets for slides and mockups, and the business and creator tools cover names, slogans and video titles.

    Threadify is free and supported by ads. Most tools run in your browser, and none of them need an account.

    Frequently asked questions

    Is Threadify free?

    Yes. All 100 free tools are free to use and you do not need an account. Threadify is supported by ads.

    Do I need an account?

    No. There is no signup or login. Open a tool and start typing.

    Is my text uploaded?

    Most tools run in your browser, so your text is not uploaded. The link previewer fetches the page you enter through our server, and previews that show an image from a web address load that image straight from its site. Threadify is supported by ads from Google AdSense, which may use cookies; see the Privacy Policy.

    Which character limits does Threadify use?

    X: 280, counted with X's weighting for links, emoji and Chinese, Japanese and Korean characters. Threads: 500. LinkedIn: 3,000. Mastodon: 500 by default, but servers can set a different limit. Facebook: 63,206. Limits can change, so check the app before posting.

    How does the thread generator split text?

    Text is split at paragraph and sentence breaks, then at words when a sentence is too long, and every post stays within the limit. You can force a break with --- on its own line.

    Why do styled bold and italic letters sometimes look odd or not show in search?

    Styled bold and italic letters are Unicode symbols. They paste almost anywhere, but screen readers may read them letter by letter and they can be harder to search. Use them for a few words.

    Does it work on mobile?

    Yes. The tools work in mobile browsers on phones and tablets, so you can paste, split and copy without installing an app.

    Can I copy the whole thread at once?

    Yes. Use Copy all for the whole thread or the copy button on a single post. You can also download the thread as a .txt file.

    Can I use Threadify for business?

    Yes. You can use the tools for personal and commercial work. Check each platform's own rules for ads, branded content and automation before you post.
