FAQs
What is UTF-8 encoding?
UTF-8 is a variable-width character encoding that can represent every character in the Unicode standard. It uses 1 byte for standard ASCII characters and up to 4 bytes for other characters.
Why do character count and byte count differ?
In UTF-8, different characters can take up different amounts of space. ASCII characters use 1 byte, while other characters like emojis or non-Latin scripts might use 2-4 bytes each.
Is this tool free to use?
Yes, our UTF-8 counter is completely free and doesn't require any sign-up.
How accurate is the byte count?
The byte count is 100% accurate as it uses the native TextEncoder API to calculate the exact UTF-8 byte length of the text.
Can I use this tool for checking database field limits?
Yes, this tool is perfect for checking if your text will fit within database field limits, especially for fields with byte-length restrictions.
Does this tool work with all types of characters?
Yes, it works with all Unicode characters, including emojis, non-Latin scripts, and special characters.
Is my text kept private?
Yes, all processing is done in your browser. We don't store or transmit any of your text.
