Split a Markdown blog post into a numbered Twitter/X thread. Smart paragraph + sentence breaks.
Free Markdown to Twitter Thread Splitter takes a long-form Markdown post and breaks it into numbered tweets that fit Twitter/X's character limit. Smart paragraph and sentence breaks, optional Markdown stripping, three numbering formats, and side-by-side card + plaintext views for easy scheduling in Buffer, Hypefury, or TweetDeck.

Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.
The splitter prefers paragraph boundaries first, then sentence breaks (period, question mark, exclamation), then word breaks, and only hard-breaks mid-word as a last resort. Adjacent short tweets get merged if their combined length fits under the limit, so you don't end up with one-word tweets that look awkward in the middle of a thread.
For shorter content that's already paragraph-sized, consider the Free Markdown to Plain Text tool as a lighter alternative.
Short (1/12) is compact and standard. Long (Tweet 1 of 12) is more explicit — better for long threads where readers might miss a short marker. Emoji (🧵 1/12) uses the thread emoji as a visual anchor — popular for signaling 'this is a thread' at a glance. Toggle off entirely if you're writing a thread where Twitter will auto-number in the UI.
By default, Markdown formatting is stripped before splitting — headings become plain lines, bold and italic markers are removed, code blocks are dropped, and inline links become text plus URL. This gives you clean tweet text that reads naturally on Twitter. Toggle off if your source is already plain text or if you want to keep the markers for a custom renderer.
For more aggressive cleanup, try the Free Markdown Minifier on your source first.
Toggle between Cards view (each tweet in its own card with copy button and live character count) and All as text view (every tweet concatenated for one-shot copy into Buffer or TweetDeck). Cards highlight any tweet that's over the character limit so you can catch issues before scheduling.
Once your thread is ready, render a preview of the source post with the Free Markdown Live Preview or Free Markdown Word Counter.
Drop in any length Markdown document.
Pick max length, min length, numbering style, and strip-markdown toggle.
Card view gives per-tweet copy; text view gives one-shot copy for scheduling tools.
