Base64 Encoder / Decoder

When to use Base64?

Base64 encodes binary data (image, file, key) into ASCII so it can travel through text channels (email, URL, JWT, data URI). Use "Encode" to convert plain text to Base64, or paste Base64 then "Decode" to read it.

Files

Load a file (image, PDF, anything) to get its Base64 representation — useful for data URIs or embedding in HTML/CSS.
