Encode any text or string into Base64 format.
Instant Encoding
Encode any text or string into Base64 format.
BulkTools's free online Base64 encoder converts any plain text, URL, or data string into Base64-encoded format instantly. Base64 encoding is widely used in web development, APIs, email systems (MIME), and data embedding.
Common use cases for Base64 encoding: Embedding images directly in HTML or CSS as data URIs, sending binary data over text-based protocols like JSON or XML, encoding credentials for HTTP Basic Authentication headers, and storing binary data in databases or configuration files.
Paste your text into the input box and the Base64 encoded output is generated in real time. No data is sent to any server — encoding happens entirely in your browser for maximum privacy and security.
