Character Counter
Count characters, graphemes and UTF-8 bytes, and see how many remain before your limit.
What this tool does
Counts characters three ways (code points, visible graphemes, and UTF-8 bytes) and compares the result with a limit you set, such as an SMS, ad headline or meta description length.
Who should use it
Anyone writing to a strict limit: ad copy, product titles, social posts, form fields with database column limits.
How it works
Code points are counted by iterating the string, graphemes use the browser's Intl.Segmenter so a flag or family emoji counts once, and bytes come from a UTF-8 encoder. The limit comparison is simple subtraction.
How to use it
- Enter or paste your text in the form.
- Adjust the options below the main box if you need to; the defaults suit most cases. Use "Load example" to see how input should look.
- Press the run button. Processing happens instantly in your browser.
- Review the result panel, then copy or download the output if the tool offers it. Use Reset to start over.
Practical example
The text "café 👍" has 6 code points, 6 visible graphemes and 10 UTF-8 bytes (é uses 2 bytes, the emoji 4).
Understanding the results
Use graphemes for what readers see, bytes when a database or API limits storage, and code points when a platform counts "characters" the Unicode way.
Limitations
Platforms count characters differently (some count emoji as two, some weight URLs). Always confirm with the target platform if the limit is hard.
Accuracy and report transparency
Results are computed in your browser from exactly what you enter. Deterministic steps (counting, parsing, encoding, validation) are verified by an automated test-suite with known answers. Where a method is a heuristic, the result panel says "estimated". No external data is used and nothing is invented.
Privacy
Your input never leaves your device for this tool. We count anonymous events (tool opened, run, copied) without storing what you typed. See the Privacy Policy.
Frequently asked questions
Why are bytes higher than characters?
In UTF-8, accented letters use 2 bytes, many symbols 3, and emoji 4. Only plain ASCII is one byte per character.
Is my data sent to your server?
No. This tool runs entirely in your browser, so the text or files you enter stay on your device. We do record anonymous counts of how often each tool is opened or run (no input data) to see which tools are useful.
How accurate are the results?
Counting, parsing, encoding and validation steps are deterministic and covered by automated tests with known answers. Anything based on a heuristic is labelled "estimated" in the result panel.
Is this tool really free?
Yes. There is no account, limit or paid plan. The site is supported by advertising, which is disclosed on our Advertising Disclosure page.
