Yes. This character counter is offered at no charge.

Do I need to sign up?

No. Use it on this page without login.

Is my text sent to a server?

No. Counting happens only in your browser; your text is not sent to Webooro servers.

What's the difference between characters and bytes?

Character count is the number of characters (including spaces and line breaks). Bytes are calculated in UTF-8: Korean characters are typically 3 bytes, English letters and numbers 1 byte. SNS and database limits often use bytes.

Are spaces and line breaks included?

Yes. Character count, word count, and bytes all include spaces and line breaks. On Twitter and similar services, spaces count as 1 character.

How many characters does an emoji count as?

In Unicode, most emoji count as 1 character, but some compound emoji (e.g. family emoji) count as 2. In UTF-8 bytes, emoji are 4 bytes each. Different platforms count emoji differently, so test in the actual service.

How many bytes is one Korean character?

In UTF-8 encoding, one Korean (Hangul) character is 3 bytes. English letters, numbers, and common punctuation are 1 byte each. Emoji are 4 bytes. This matters when a database column uses a byte-based limit like VARCHAR(255).

Where can I find character limits for specific platforms?

Twitter/X: 280 characters. Instagram caption: 2,200. SMS (English): 160. SMS (Korean): ~70. YouTube title: 100. Use this counter to write and check length in real time against those limits.

📋 How to Use

Type or paste text into the input area.
Character count, word count, and byte count update as you type—there is no separate “count” button.
Clear the box or paste new text anytime.

Your text is processed only in the browser and is not sent to our servers.

💡 Example

📱 Social media post length

Paste your Twitter/X draft and check if it's within 280 characters. For Instagram captions, keep under 2,200 characters to avoid truncation. The counter updates in real-time so you can trim as you go.

📧 SMS and email length

Standard SMS is limited to 160 characters (70 for Korean text in some carriers). Check the byte count when writing Korean — a single Korean character is 3 bytes in UTF-8, so a 140-byte limit fits about 46 Korean characters, not 140.

💻 Database column planning

When designing a VARCHAR(255) column, paste your longest expected input here to see the byte count. Korean text uses more bytes per character than ASCII, so a 255-byte column can hold far fewer Korean characters than English ones.

✨ Why show bytes as well as characters?

Korean text, emoji, and mixed scripts can use many more bytes than “characters” in UTF-8. Some services limit by bytes, not glyphs—so we show both.

Word count splits on whitespace; it is a simple heuristic. English is closer to “words”; Korean phrases may not match every app’s definition—use as a rough guide.

Highlights

Shows characters, words, and bytes together.
Paste long text and see instant updates.
Your input is not sent to our servers.

Useful for Twitter/X limits, blog titles, product name fields, VARCHAR sizes, and draft length checks.

Good use cases

Before posting to a forum with a character cap
When a form says “max bytes” instead of characters
Rough draft length for essays or reports
Quick checks without opening a word processor

Compared with other options

Word processors also count text, but this page is fast when you only have a browser. Nothing is uploaded to our servers.

Each platform defines “character” differently (emoji, spaces)—always double-check in the target app before final submit.
