Question 1

What is Base64 encoding?

Accepted Answer

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

Question 2

How do I encode text to Base64?

Accepted Answer

Enter your text in the input field and click 'Encode'. The tool converts each character to its binary representation, then encodes it using the Base64 alphabet (A-Z, a-z, 0-9, +, /).

Question 3

Is Base64 encryption?

Accepted Answer

No, Base64 is encoding, not encryption. It's easily reversible and provides no security. Anyone can decode Base64 text. For security, use proper encryption algorithms like AES.

Question 4

Why does Base64 make data larger?

Accepted Answer

Base64 increases data size by about 33% because it represents 6 bits of data using 8-bit characters. This overhead is the tradeoff for making binary data text-safe.

Question 5

What are common uses of Base64?

Accepted Answer

Common uses include: embedding images in CSS/HTML (data URLs), encoding email attachments (MIME), storing binary data in JSON/XML, and encoding credentials in HTTP Basic Auth.
