What is File Size Converter (Bytes, KB, MB, GB, TB)?
File Size Converter translates digital data storage units across Decimal base-10 (Bytes, KB, MB, GB, TB, PB) and Binary base-2 (Bytes, KiB, MiB, GiB, TiB, PiB) measurement systems with exact mathematical accuracy.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
