Frequently asked questions

What is Count Bytes used for?

Use it to check a size limit, a database column, or a hash input length.

Fill in Input. This field is required. Click Run and copy the result under the form.

What can I paste or upload into Count Bytes?

What output does Count Bytes give me?

A single integer. ASCII is one byte per character. Many other characters are two to four bytes.

Is Count Bytes free, and is my input private?

Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.

Does the box’s character counter match this?

Not always. Browsers often count code units or graphemes. This result is the UTF-8 byte length the tool would hash or store.

Inputs are processed in memory only and are not saved to disk or the database. Data exists only for the duration of your request.
