About this base64 encoder & decoder
Base64 turns arbitrary bytes into plain ASCII so they survive systems that only handle text — data URIs, email attachments, JSON payloads and tokens.
This handles Unicode correctly by encoding to UTF-8 first, which is where most naive Base64 tools break.
How to use it
- Paste text or Base64 into the box.
- Pick Encode or Decode.
- Copy the result; switch on URL-safe mode if it is going in a query string.
Base64 Encoder & Decoder — FAQ
Is Base64 encryption?
No. It is an encoding, trivially reversible by anyone. Never use it to protect secrets.
Why does my decoded text look wrong?
Usually a UTF-8 issue. This tool decodes as UTF-8, which fixes most mojibake.
