This file size converter helps you convert storage and data sizes between bytes, KB, MB, GB and TB. It uses the binary standard (base 1024), which is common for RAM, file systems and many tools.
Use it to understand downloads, disk usage, backups, cloud storage, videos, photos, archives (ZIP), or to compare sizes shown by different operating systems. All calculations run locally in your browser.
Binary units used: 1 KB = 1024 B, 1 MB = 1024 KB, etc.
