Twitter / X Character Counter Online
Runs 100% in your browser — your files never leave your device.
X's 280-character limit is not a plain character count: Japanese, Korean, and Chinese characters weigh two units, and every link counts as 23 no matter its length. Paste your post and get the same weighted count the composer applies, live as you type — so what fits here fits there.
