Base64 to Hex Converter

Base64 and hex are both ways to represent binary data as text. Hex (two characters per byte) is more readable for low-level inspection of binary content — seeing individual byte values. Cryptographic operations, binary protocols, and debuggers commonly work in hex.

No. Both formats represent the same underlying binary data — just in different encodings. Base64→hex and hex→Base64 are lossless reversible transformations. The binary content is identical throughout.

Hex represents each byte as 2 characters; Base64 represents every 3 bytes as 4 characters (~1.33× overhead). Hex has a ~2× overhead over raw bytes. So hex output is approximately 50% larger than equivalent Base64 output.
