Hi, max hwang here, full-stack developer in Korea.
Most character counters give you one number. The trouble is that platforms do not agree on what a character is: a family emoji is one grapheme but several UTF-16 code units, and SMS switches from GSM-7 to UCS-2 as soon as one character falls outside the basic table. So this page counts graphemes, UTF-8 bytes and words separately, marks the exact spot where each platform would cut, and reports SMS segment counts.
Nothing is sent anywhere. The worker serves static files and all counting happens in your browser.
There are four sub-pages for cases the main table cannot express: pixel-width truncation for meta descriptions and title tags using canvas.measureText, the YouTube 100 character cap versus the visible cut, and a Discord splitter that keeps code fences and emoji intact across chunks.
