How to use Chunkify Unicode
- 1. Paste the text to split. Enter the string you want broken into fixed-size pieces. Length is measured in code points, so multi-byte characters count as a single unit each.
- 2. Set the chunk size and separator. Choose the Chunk size to decide how many code points go in each group, and set the Separator that joins the groups, such as a space, comma or newline.
- 3. Review the grouped output. Check that the output splits your text into evenly sized chunks with the separator inserted between each group, with the final chunk possibly shorter if the length does not divide evenly.
- 4. Copy the chunked text. Copy the result into a format that expects fixed-width groups, such as a serial number, a hash display or a data entry field with grouped digits.
When to use Chunkify Unicode
Chunkify Unicode splits a string into fixed-length groups separated by a character of your choice, working by code point so it handles accented and multi-byte text correctly. Use it whenever raw text needs to be broken into evenly sized pieces for display or entry.
- Formatting a license or serial key. A generated key needs to display as groups of four characters separated by dashes. Chunking the raw string with size 4 and a dash separator produces the expected format instantly.
- Breaking a hash into readable blocks. A long hex digest is hard to read as one unbroken line. Splitting it into 8-character chunks with spaces between them makes it easier to compare by eye.
- Preparing fixed-width data imports. A legacy system expects a field padded and grouped into fixed chunks. You use this tool to reshape a raw string into the exact grouping the import format requires.
- Wrapping long identifiers for display. A UUID or token needs periodic breaks so it wraps cleanly in a narrow UI column instead of overflowing as one continuous string.

About the Chunkify Unicode tool
Chunkify Unicode runs as plain JavaScript in your browser tab, with no server behind it. Quickly split Unicode text into chunks of constant length. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Unicode Tools section, 98 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 2 settings, including Chunk size and Separator, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Chunkify Unicode cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
