The Change Integer Base tool lets you instantly convert whole numbers between decimal, binary, octal, and hexadecimal formats. Whether you’re working with logs, scripting a config, or decoding values from a protocol, it’s got you covered. Just paste in any integers and choose the base you want. Everything updates live, and nothing ever leaves your browser.
This is a handy little utility when you’re bouncing between systems that expect different numeric formats. Want to see what 255 looks like in hex? Flip the switch. Need all values in binary for bitmask operations? It’s just one click away. Even negative numbers are handled correctly using standard base conversions.
It also supports file import/export, so you can load full datasets or share converted results fast.
How to Use:
- Paste or import integers (one per line)
- Choose output format: Binary, Octal, Decimal, or Hex
- Use Ignore invalid values to skip non-numbers
- Toggle Maximize output if you’re working with a long list
- Click Convert to apply the new base
- Use Copy Output or Export to File to save results
- Use Clear All to reset everything
What Change Integer Base can do:
This tool is ideal for quickly converting between numeric systems. You can toggle output bases, ignore bad data, and even export your results for use in other projects. It’s perfect for debugging, teaching, coding, or working with system-level integers in various bases.
Example:
Before:
10
255
4096Output (Hex):
a
ff
1000Common Use Cases:
Perfect for developers working with bitwise ops, network packets, or any project that shifts between number bases. Teachers and students use it too it’s a quick way to demonstrate base conversion on real data.
Useful Tools & Suggestions:
After using Change Integer Base, you might want to try Convert Binary Base to Integers or Convert Hex Base to Integers to work with specific systems directly. And if you’re switching between a lot of formats, Convert Octal Base to Integers helps round out your base toolkit.
