How it works

Three steps, no setup

1

Paste your text or Base64

The tool auto-selects the right direction based on which box you edit.

2

Read the conversion

UTF-8 multi-byte characters are handled correctly, not just ASCII.

3

Swap and copy

Flip input and output to chain conversions, then copy the result.

Common questions

Frequently asked questions

Is Base64 encryption?
No — it is a reversible text encoding, not a security mechanism. Anyone can decode it instantly.
Why does my emoji look broken after decoding?
That usually means the original string was encoded assuming a different character set. This tool assumes UTF-8 on both ends.
