Understanding Base64 Encoding

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data.

Common use cases include embedding images in HTML/CSS or sending attachments in emails.

Base64 Tool FAQ

1. Is Base64 a form of encryption?

No. Base64 is an encoding scheme, not encryption. It is used to transform data into a safe format for transmission, but it does not provide any security or privacy.

2. Can I encode images into Base64?

Yes, though this specific tool is optimized for text. Encoding images allows you to embed them directly into your website's code to reduce HTTP requests.

3. Is my data kept private?

Yes. All encoding and decoding are performed locally in your browser using JavaScript. No data is sent to our servers.
