Frequently asked questions

Is my text uploaded anywhere?
No. The character counter runs 100% in your browser. Your text never leaves your device and is not stored anywhere.
Why does X count differently?
X weights characters: every link counts as a flat 23 characters, and emoji and CJK characters (e.g. Chinese/Japanese) count as 2 each. This tool replicates exactly that.
Which platforms are supported?
X (280), LinkedIn (3,000), Instagram (2,200), Facebook (63,206) and Bluesky (300) — each with its current character limit.
