바이트 변환기 — KB MB GB TB

Convert between bits, bytes, KB, MB, GB, TB and IEC KiB/MiB/GiB/TiB. Drop a PDF or any file to read its exact size—built for EU searches like “Bytes umrechnen” and disk vs OS size confusion.

Type in any field — all units update instantly. SI uses 1000 (disk marketing); IEC uses 1024 (OS / RAM). Drop a PDF or any file to read its exact byte size.

Bytes converter — KB, MB, GB, TB (SI & IEC)

Europeans search heavily for “Bytes umrechnen”, “convertisseur octets” and “convertidor de bytes”. Hard-drive makers use SI (1 GB = 1,000,000,000 bytes); Windows and macOS often show IEC (1 GiB = 1,073,741,824 bytes). This tool shows both so a “1 TB” disk and a 500 MB PDF make sense.

  • PDF / file → bytes: drop any file to fill the Bytes field with the exact size, then see KB/MB/GiB instantly.
  • Bit ↔ byte: network Mbps vs file MB (8 bits = 1 byte).
  • Pair with Base64 size or PDF to Base64 when you need wire size after encoding.

자주 묻는 질문

Why is my 1 TB drive only ~931 GB?

Manufacturers use SI (1 TB = 10¹² bytes). Operating systems often show GiB (1024³). 10¹² ÷ 1024³ ≈ 931 GiB—nothing is missing.

Can I convert a PDF to bytes?

Yes: drop the PDF (or any file) on this tool. The Bytes field shows the exact file size; other units update instantly.
