How to use Increment Unicode Values
- 1. Paste the text to shift. Enter the characters you want to shift into the input pane. Each one is treated by its underlying code point value, regardless of what script it belongs to.
- 2. Set the Amount. Enter how many positions to add to every code point. A positive amount shifts forward through Unicode, for example turning A into B with an amount of one; a negative amount shifts backward.
- 3. Copy the shifted result. Every character in the input is replaced by the character that many code points ahead. Copy the result once you confirm the shift produced the characters you expected.
When to use Increment Unicode Values
Increment Unicode Values shifts every character in your text forward or backward by a fixed number of code points. It is a low-level way to explore adjacent characters or build a simple substitution effect across a whole string at once.
- Building a simple Caesar-style cipher demo. A cryptography lesson wants a live example of shifting letters by a fixed offset. Setting the amount to three and shifting a word shows how each letter maps to one three positions later.
- Exploring which character follows another in a block. You are curious what character comes right after a specific one in Unicode, for example what follows the last digit. Shifting by one on that single character reveals its immediate neighbor.
- Generating a sequence of related glyphs. A design mockup wants a row of characters that step visually across a range, like sequential box-drawing pieces. Repeated small shifts step through the neighboring code points.

About the Increment Unicode Values tool
Increment Unicode Values runs as plain JavaScript in your browser tab, with no server behind it. Quickly increase Unicode code point values. 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 the Amount setting, and the result refreshes the moment you change it. 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
Is Increment Unicode Values free to use?
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?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
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?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
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.
