What is Base64 encoding?
Base64 turns any text or binary data into a plain-text string using 64 safe characters (A–Z, a–z, 0–9, + and /). It’s how data like images or credentials get carried inside JSON, HTML, emails, and URLs where raw bytes would break.
This tool encodes and decodes right in your browser — nothing is uploaded or stored. It’s fully UTF-8 safe, so emojis and non-English text work correctly.
Frequently Asked Questions
Is Base64 encryption?
No — Base64 is encoding, not encryption. Anyone can decode it instantly. It makes data safe to transport, but it does not protect or hide it. Never use it to secure passwords or secrets.
Does it work with emojis and other languages?
Yes. This tool is UTF-8 safe, so emojis, Bangla, Arabic, and any Unicode text encode and decode correctly without corruption.
Is my data private?
Completely. Encoding and decoding happen in your browser with JavaScript. Nothing is sent to a server, logged, or saved.
Why did decoding fail?
The input wasn’t valid Base64 — it may have extra characters, spaces, or be plain text. Check that you pasted a proper Base64 string.
