Byte Converter
Convert data sizes between bits, bytes, decimal units, and binary units with clear, precise results.
A QUICK WALKTHROUGH
How to use this tool
- Enter a non-negative value and choose its unit.
- Convert to see decimal and binary storage units.
- Copy the complete conversion locally from your browser.
Decimal and binary units
Decimal units use powers of 1000: KB, MB, GB, TB, and PB. Binary units use powers of 1024: KiB, MiB, GiB, TiB, and PiB.
Clear input validation
Enter a finite, non-negative decimal value without separators or unit text. Invalid, negative, and impractically large values are rejected before conversion.
Private browser conversion
Your value is parsed and converted locally in your browser. Nothing is uploaded or stored.
GOOD TO KNOW
Common questions
What is the difference between KB and KiB?
KB is 1,000 bytes, while KiB is 1,024 bytes.
Can I convert bits?
Yes. Select Bits (bit) as the input unit; results include bytes and all supported storage units.
Are decimal fractions supported?
Yes. Values such as 1.5 or 2e3 are accepted, but separators and unit text are rejected.
Does this tool upload my data?
No. Conversion runs entirely in your browser.
