Frequently asked questions
How many MB are in a GB?
1 GB is 1000 MB in the decimal system; the binary equivalent is 1 GiB = 1024 MiB.

Mobile plans and most drive labels use decimal GB (1000-based). Operating systems may show binary sizes, so a 500 GB drive can look like 465 GiB.

No. GB to MB 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 GB to MB 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.
