About this tool
How it works
Encodes UTF-8 bytes to Base64 and reverses the byte sequence when decoding.
A practical way to use it
Inspect a Base64 configuration value or encode a short Unicode test payload.
Use results as a practical aid, and verify important decisions against your own source data and qualified guidance.
