Frequently asked questions
Why are there two kinds of kilobyte and gigabyte?
SI units (kB, MB, GB) are powers of 1000, while binary units (KiB, MiB, GiB) are powers of 1024. Both are listed so you can convert between them exactly.
How precise are the results?
Results are rounded to 10 significant digits, which removes floating-point noise while staying far more precise than everyday use needs.
Are my files uploaded anywhere?
No. Unit Converter runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Unit Converter really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
Does it work offline?
Once the page has loaded, processing happens locally, so it keeps working even if your connection drops.
