How It Works

Base64 encoding is commonly used to encode binary data as ASCII text for transmission over text-based protocols.

Base64 uses 64 printable characters (A-Z, a-z, 0-9, +, /) to represent binary data. Every 3 bytes of input produces 4 bytes of Base64 output.

Common uses include email attachments, embedding images in HTML/CSS, and API data transmission.

What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text format using 64 printable characters.

When should I use Base64?

Use Base64 when you need to transmit binary data over text-based protocols like HTTP or email.

Is Base64 encryption?

No, Base64 is encoding, not encryption. It can be easily decoded and doesn't provide security.
