CHARACTER AND BYTE COUNTER
Count characters and bytes
as you type.
Check text for applications, social posts, manuscripts, forms, or storage limits with several counting rules at once.

UTF-8 byte size can differ from the visible character count, especially for non-Latin scripts and emoji.
Examples
Multibyte text
Many Korean characters occupy three UTF-8 bytes even though each is one visible character.
Emoji sequences
When browser support allows, joined emoji are counted as one user-perceived character.
Whitespace-separated words
Words are groups separated by spaces, tabs, or line breaks rather than a linguistic analysis.
How the counts work
Platforms may count visible characters and storage size differently, so each metric is shown separately.
User-perceived characters
Modern browsers group combining marks and emoji sequences when possible. Older support falls back to Unicode code points.
Bytes use UTF-8
English letters usually use one byte, while many other characters use more. Compare bytes when an API or database has a size limit.
Words use whitespace
Groups separated by spaces, tabs, or newlines count as words. Results can differ from a publisher's own rules.
Scope and limitations
Use the metric required by the destination rather than treating every count as interchangeable.
Words are not linguistic tokens
The word count splits on whitespace and does not run a language-specific morphology analyzer.
UTF-8 is not an SMS limit
The byte total describes UTF-8 storage, not carrier-specific SMS segmentation or database encoding.
Browser support can differ
Grapheme grouping uses Intl.Segmenter when available and otherwise falls back to Unicode code points.
Character counter FAQ
Why can one emoji use several bytes?
Visible symbols can contain multiple Unicode code points, and each code point may require multiple UTF-8 bytes.
Are spaces included?
Both totals are shown: one includes whitespace and one excludes it.
Does the result match every publisher?
No. Compare the destination's own counting rule, especially for emoji, line breaks, and words.
