Character Counter
Live character, no-space and byte counter with an optional limit indicator.
About Character Counter
The Character Counter reports three related measurements as text changes: JavaScript string length, the same total after all whitespace is removed, and the number of bytes produced by UTF-8 encoding. Character length is useful for form limits, the no-whitespace count helps with compact identifiers or assignment rules, and byte length matters when a database field, API or file format has a storage ceiling.
A custom numeric limit provides a progress bar and a current-count display such as “125 / 280 characters.” Change the limit to match the destination you are preparing text for. The limit is a visual reference only: it does not truncate the input or block additional typing, so you can revise naturally and see exactly how far the draft extends.
Counting takes place locally as you type or paste. UTF-8 represents plain ASCII characters in one byte, while accented letters, many non-Latin characters and emoji commonly require multiple bytes. Browser string length can also count a visible emoji as more than one code unit, which is why platform-specific counters may report a different “character” total.
How Character Counter works in practice
- 1Type or paste your text into the counter box.
- 2Enter a positive limit matching the form, field or publishing destination you are targeting.
- 3Review the live character, without-spaces and UTF-8 byte totals beneath the progress bar.
- 4Edit the source until the relevant total satisfies your requirement, then select it for use at the destination.
Jobs this tool is built for
- Drafting a social post, profile biography or advertising field with a published character allowance.
- Checking a page title or meta description against an editorial length target.
- Estimating UTF-8 payload size for a database column, API request or device protocol that specifies bytes.
- Measuring a username, slug or code-like value both with and without embedded whitespace.
What you can do here
- Live JavaScript string-length count
- Count with spaces, tabs and line breaks removed
- UTF-8 byte count through the browser TextEncoder
- Editable positive numeric limit
- Progress bar capped at the full width of its track
Limits and honest caveats
- The tool does not enforce the custom limit or remove excess text; the numeric count is the reliable indicator when input exceeds the target.
- Some services count Unicode symbols, URLs or line breaks using their own rules, so confirm a final draft in the destination platform.
- Your input is processed in the browser and is not intentionally saved by this counter.
Common questions about Character Counter
What is the difference between characters and bytes?
Characters describe browser string length, while bytes describe encoded storage size. Basic Latin text is often one UTF-8 byte per character, but many other symbols require more.
Why can one visible emoji add two characters?
JavaScript string length counts UTF-16 code units rather than user-perceived symbols. Many emoji use two code units, and joined sequences can use several.
Does the limit prevent me from typing too much?
No. It is a comparison target and progress display, not an input restriction. Watch the current number shown before the slash.
Does pasting rich text keep formatting?
No. Input is treated as plain text, so rich-text styling is not part of the count.
