Conversor de tamanho de ficheiro

In an era where a single smartphone photo can exceed 10 megabytes and enterprise databases routinely measure in petabytes, the ability to quickly and accurately convert between digital storage units has become an essential everyday skill. Our data storage converter handles the full spectrum — from bits and bytes at one end to petabytes and exabytes at the other — and crucially supports both the decimal (SI) standard (where 1 kilobyte = 1,000 bytes, used by hard drive manufacturers and storage vendors) and the binary (IEC) standard (where 1 kibibyte = 1,024 bytes, used by operating systems). This distinction explains why a 500 GB hard drive appears as only around 465 GiB in Windows or macOS — a discrepancy that confuses countless users every day.

Understanding data sizes is particularly valuable when you are working with developer tools. If you are handling JSON payloads, API responses or configuration files and need to check their encoded size, our Base64 Encoder/Decoder shows the input and output character counts alongside its conversion — helping you estimate the overhead of encoding binary data as text for transmission across web services.

For a broader range of measurement conversions beyond data storage, our all-in-one Unit Converter covers length, weight, volume, area and speed — making it the perfect complement to this tool when you need to switch between multiple measurement systems in a single working session.

Por que o seu disco de 1 TB só mostra 931 GB no Windows

Os fabricantes usam o padrão decimal (SI) (1 KB = 1.000 bytes), os sistemas operativos o padrão binário (IEC) (1 KiB = 1.024 bytes). Isto explica a discrepância entre a capacidade anunciada e a apresentada.
