What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that converts binary data into ASCII characters. It's commonly used to embed images in HTML/CSS, encode email attachments, and transmit binary data in text-only protocols.

How do I encode text to Base64?

Paste your text into the input field and click Encode. The Base64-encoded string appears instantly. You can also decode Base64 back to plain text by pasting encoded text and clicking Decode.

Is Base64 encoding the same as encryption?

No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 text. It's used for data transport, not security. For encryption, use tools like AES or RSA.
