Question 1

What is Base64 encoding?

Accepted Answer

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

Question 2

How do I encode text to Base64?

Accepted Answer

Paste your text in the input field and click Encode. The Base64 string appears instantly. Copy it with one click for use in your code or API.

Question 3

Is Base64 encoding the same as encryption?

Accepted Answer

No. Base64 is encoding, not encryption — anyone can decode it. It is designed for safe data transport, not security. Use proper encryption for sensitive data.

Question 4

Can I encode images and files to Base64?

Accepted Answer

Yes. Drag and drop any file to convert it to a Base64 string. For images, a data URI is generated that you can paste directly into HTML or CSS.
