How to use Truncate Hex Values
- 1. Paste the hex value. Enter the hexadecimal string you want shortened, such as abcdef12, which might be longer than the field or display you are targeting can hold.
- 2. Set the Keep length. Choose how many digits should remain after truncation, matching the width your destination field, ID or display actually needs.
- 3. Choose the Keep side and copy. Pick Left to keep the leading digits or Right to keep the trailing digits, then copy the shortened value into wherever the fixed-width hex is expected.
When to use Truncate Hex Values
Truncate Hex Values cuts a hex string down to a fixed number of digits, keeping either the leading or trailing portion. Use it whenever a display, filename or field has a strict width and a full hex value would not fit.
- Shortening a commit hash for display. A version control interface or log line only has room for a short prefix of a hash, and truncating to the first several digits gives a recognizable short form.
- Fitting a value into a fixed-width legacy field. An older system's database column only stores a fixed number of hex characters, and you need to trim a longer value down to fit without erroring out.
- Extracting a suffix from a longer identifier. You only care about the last few digits of a long hex ID, such as a device serial number's trailing bytes, so you keep the right side and discard the rest.
Examples

Input

Output
abcd
Keep last 4
Input
abcdef12
Output
ef12
