How File Size Conversion Works
Digital storage units are calculated using binary values, where each step increases by a factor of 1024. For example, 1 KB = 1024 Bytes, 1 MB = 1024 KB, and 1 GB = 1024 MB.
This File Size Converter automatically applies these calculations, allowing you to quickly understand file sizes when compressing data, uploading files, estimating storage needs, or optimizing applications.
