Number Converter
What is this tool?
The ToolsMatic Number Converter flips values between decimal, hexadecimal, and binary. It is helpful for developers, students, and hardware tinkerers who need quick base conversions without a calculator. It keeps your focus on the math you care about instead of fiddling with syntax or separators.
By presenting all three bases together, it makes it easier to spot patterns, check bitmasks, and translate color codes or register values quickly.
How to use this tool
Enter a value, choose the base of that input, and click Convert. The tool outputs the other bases immediately, handling lowercase hex and stripping whitespace automatically.
Use it to confirm CSS hex colors against decimal RGB values, or to translate binary flags into readable hex during debugging. If a value fails, double-check the selected base and rerun; errors are cleared on the next conversion.
When working with microcontrollers or network packets, paste register values, convert them, and compare against documentation without leaving the browser.
Who should use it?
Developers working with color codes or bitmasks, embedded engineers translating registers, and learners studying number systems all benefit from a fast converter.
Security analysts reviewing hashes, firmware engineers testing addresses, and students in computer architecture courses can keep this open as a lightweight helper.
Why use ToolsMatic for this?
ToolsMatic keeps the interface distraction-free and loads instantly, so you can check a value mid-debug without leaving the browser.
The familiar ToolsMatic layout lets you pair this with the UUID Maker or Regex Tester while examining payloads, avoiding context switching between tools.
Privacy & performance
Conversion runs locally with built-in JavaScript parsing. No data leaves the page, and the script is tiny for strong performance.
With no external requests, the converter works offline-friendly and remains fast on low-powered machines. Your inputs are never transmitted, keeping sensitive values private.
