Frequently asked questions
How do I decode a 32-bit integer into bit fields?
Enter the value as decimal, 0x hex or 0b binary, define named bit ranges by start bit and width, and the Bitfield Inspector shows each field's value live with a colour-coded bit display.
Can I name the fields?
Yes, you define named bit-fields and see each one's decimal and hex value. Presets such as a GPIO port and Unix permissions are included.
Is it limited to 32 bits?
No, you can switch between 32-bit and 64-bit width.
Is my data uploaded to a server?
No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
