Text Splitter

Paste long text and this tool splits it into chunks of a fixed character count, so you can preview and copy each piece individually. Nothing is sent to a server — everything runs in your browser.

How to use it

  1. Paste your text: Enter the text you want to split into the left-hand box.
  2. Set the chunk size: Enter the number of characters per chunk in the "Chars per chunk" field. The default is 500.
  3. Check the result: The right side lists the chunks in order, each cut to the size you set. Changing the text or the chunk size re-splits it instantly.
  4. Copy: Click the 📋 button on any chunk to copy just that chunk's text to your clipboard.

Splitting and copying happen entirely in your browser. The text you paste is never sent to or stored on a server.

When is this useful?

Some forums, chat apps, and AI chatbot input boxes limit how many characters you can paste at once. This tool pre-splits long text into pieces of the size you choose, so you can copy and paste just the piece you need, in order, without losing your place. It cuts strictly from the start, in the original order — no reordering or reformatting.

Frequently Asked Questions

How is the character count measured?

By JavaScript string length (.length). Most characters count as one, but some emoji made of a surrogate pair can count as two.

Is my text sent anywhere?

No. Splitting and copying are handled entirely in the browser and never sent to or stored on a server.

What happens if I leave the chunk size at 0 or blank?

It's automatically clamped to a minimum of 1, so the text is split one character at a time.

Is the last chunk always the same size as the others?

No. The last chunk only contains whatever characters are left, so it can be shorter than the size you set.

Are line breaks and spaces in the original text preserved?

Yes. The text is cut strictly by character count with no regard for word or line boundaries, so line breaks and spaces stay exactly where they were in the original.
