One task, zero friction: convert between bytes, kb, mb, gb, and tb. Data Storage Converter runs right in your browser as part of ToolsMonk's converters lineup: no installs, no account, and nothing to configure before you start.
People reach for it most often when they need converting a file or storage size between mb, gb, and tb, understanding why a '1 tb' drive shows less usable space, and translating bandwidth or quota figures into familiar units. With nothing to install, an unexpected one-off job takes no longer to start than your regular routine.
Data Storage Converter is designed for people who want a practical, privacy-friendly workflow with instant results inside the larger ToolsMonk library.

Whether you're a professional, student, or casual user, it provides instant, accurate results right in your browser without requiring any software installation or account creation.
All processing runs locally in your browser, so your files and data never leave your device. The interface adapts to any modern browser and screen size, so the Converters workflow you rely on at a desk is the same one you get on a tablet or phone.
Data Storage Converter translates between bytes, KB, MB, GB, TB and larger units, and crucially supports both binary (1024-based) and decimal (1000-based) interpretations, the distinction behind a surprising amount of everyday confusion.
That confusion peaks with drive capacity. Manufacturers sell a '1 TB' drive as a trillion bytes (decimal), but operating systems frequently count in binary, where a gigabyte is 1,073,741,824 bytes, so the same drive reads as about 931 GB. Nothing is missing; the two systems simply count differently, and seeing both side by side makes it click.
The binary units (KiB, MiB, GiB) exist precisely to remove this ambiguity, even though casual usage still says 'MB' for both. The rule of thumb: storage marketing and bandwidth use decimal, while OS file sizes and RAM use binary, so match the base to your context and the numbers reconcile.
Conversion runs in your browser with nothing uploaded, across the full range from bytes to terabytes and beyond. Pair it with the other ToolsMonk converters for everyday technical reference.
When reconciling drive space, remember marketing uses decimal (1000) while your OS likely uses binary (1024)
Use the binary base for RAM and OS file sizes; decimal for storage marketing and bandwidth
If two tools disagree on a size, a binary/decimal mismatch is almost always why
