Base64 to Hex Converter — Both Directions, Instant

Convert between Base64 and hexadecimal representations of binary data instantly — two different but equally common ways of representing raw bytes as text, useful when a tool or API gives you one format but you need the other.

How to use Base64 to Hex

1. Paste your Base64 or hex string.
2. Read the converted result in the other format.
3. Copy the output.

Frequently asked questions

Why are there two different ways to represent binary data as text?

Hex is simpler to read byte-by-byte but roughly doubles the size; Base64 is more compact (about 33% overhead) which is why it is preferred for things like embedding binary data in text formats such as JSON or URLs.

Is my data uploaded anywhere?

No. Conversion runs entirely in your browser.

Does it handle padding characters correctly?

Yes — Base64 padding (=) is handled correctly in both directions.
