How to use Increment Hex Values
- 1. Provide the hex numbers. Paste whole hexadecimal values into the input pane, one per line or separated by spaces. The tool does genuine arithmetic on each, so ff plus one correctly rolls over to 100.
- 2. Set Increment by. Increment by is the quantity added to every number. Leave it at 1 to step to the next value, or use a stride like 10 hex to jump through evenly spaced addresses.
- 3. Copy the advanced values. The output lists each input plus your increment, carries and all. Copy the results into your linker script, packet builder or notes, or re-run the tool to keep advancing.
When to use Increment Hex Values
Increment Hex Values performs true addition on hexadecimal numbers so you never have to round-trip through decimal. It shines when you need the next address, ID or offset in a hex-denominated system, and it handles whole lists at once, keeping a column of related values in lockstep.
- Computing the next free address. A firmware image ends at 0x7fff and the bootloader wants the following sector. Adding one gives 8000 instantly, with the carry across all four digits handled for you.
- Advancing transaction or frame counters. While hand-crafting test frames for a serial protocol, each message needs the previous counter plus one. Paste the current hex counter, increment, and drop the new value into your payload.
- Laying out register offsets. Peripheral registers often sit 4 bytes apart. Paste the base offset list and increment by 4 to produce the next bank of addresses for a header file, without any manual hex addition.
- Fixing IDs that are one short. An import assigned hex keys starting at 0 when the target system expects them to start at 1. Increment the entire exported column in one operation before re-importing.

About the Increment Hex Values tool
Increment Hex Values runs as plain JavaScript in your browser tab, with no server behind it. Increase the value of a hexadecimal. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Hex Tools section, 108 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 Increment by 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 Hex 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.
