What is Length limits?
Essays, meta descriptions, tweets, SMS and API fields all carry limits — and they are not all measured the same way, which naive counters gloss over.
Count words, characters and lines

Type or paste text, or load a file up to 5 MB — counted locally.
Click Run to see words, characters, non-whitespace characters, lines and UTF-8 bytes.
Download the counts as JSON for reports or automated checks.
Five metrics: words (via Intl.Segmenter, so languages without spaces count correctly), characters (Unicode code points), non-whitespace characters, lines, and the UTF-8 byte size.
Characters are counted as Unicode code points, so an emoji with modifiers may count as several code points — but the byte count reflects its true UTF-8 size honestly.
API limits, database fields and SMS segments are usually specified in bytes, not characters. UTF-8 byte counting gives you the number that actually matters for those limits.
No. All counting happens instantly in your browser — your text never leaves your device.
Here is what each format is for, and when converting any text into exact counts is the right move.

What is Precise counts?
Word segmentation that handles CJK text, character counting by code point, plus the UTF-8 byte size that byte-based limits actually enforce — all shown together.
When you need it
Use it to hit essay and application limits, size meta descriptions and ad copy, check SMS or API payload budgets, or audit multilingual text where naive space-splitting miscounts words.
