Split & Copy
Break long text into chunks and copy each part individually.
Deep Dive
Split a long block of text into equal-sized chunks of N characters, useful for pasting into character-limited inputs like SMS, Twitter (legacy), or form fields. Each chunk is displayed separately and can be individually copied. Runs entirely in the browser.
Who uses this?
- Splitting a long message to send over SMS
- Breaking a prompt into chunks for a character-limited API
- Dividing a large text for manual entry into multiple fields
- Preparing paginated content for a multi-step form
Examples
Input
Hello, this is a long message.Output
Chunk 1: 'Hello, thi' | Chunk 2: 's is a lon' | Chunk 3: 'g message.'Common Errors & Fixes
Last chunk is empty
This happens when the total length is an exact multiple of the chunk size. The tool may generate a trailing empty chunk — safely ignore it.
Emoji characters cause misaligned chunks
Emoji are multi-byte characters. If character count matters, count code points, not bytes. Enable Unicode-aware mode if available.
Expert FAQ
Does the splitter cut words mid-way?
By default, yes — it splits at exactly N characters. Enable 'Split at word boundary' to avoid cutting words in half.
What is a good chunk size for SMS?
Standard SMS supports 160 characters. If you use Unicode/emoji, the limit drops to 70 characters per segment.
Can I split by line count instead of character count?
Most implementations split by character. For line-based splitting, use the Text Utility tool's line operations.
