About SNS Character Counter

SNS Character Counter is an essential free tool for anyone publishing the same draft across multiple social platforms. It instantly compares character limits for 9 major services: X (280), Instagram (2,200), TikTok (2,200), Bluesky (300), YouTube descriptions (5,000), LinkedIn (3,000), Threads (500), LINE (500), and Facebook (63,206).

See remaining characters update in real time as you type, making it immediately clear which platforms need content adjustments. Ideal for marketers, creators, social media managers, recruiters, and anyone coordinating multi-channel posts.

Features accurate grapheme cluster counting that handles emoji correctly, unlike simple character counters. Browser-based with no signup required — runs entirely on your device so drafts stay private. Eliminate the tedious task of checking each platform individually; this single tool shows you everything at once for efficient content optimization.

How to use SNS Character Counter

Type your draft into the text area or paste an existing post.
Review the remaining count and progress bar for X, Instagram, Threads, TikTok, Bluesky and more.
Trim or rewrite the platforms marked in warning or over-limit colors, then check the result again.
