How to use Base64 Encoder

Type or paste your text (or drop a file), and the tool encodes it to a Base64 string live.

Frequently asked questions

What is Base64?

Base64 encodes binary data into 64 ASCII characters (A—Z, a'z, 0–9, +, /) making it safe to transmit in text-based protocols.

When is Base64 used?

Embedding images in HTML/CSS, encoding email attachments (MIME), and transmitting binary data in JSON/XML APIs.

Does Base64 encrypt data?

No — Base64 is encoding, not encryption. Anyone can decode it. Use it only for format compatibility, not security.
