🔐 Base64 Encode / Decode

Base64 Encode & Decode — Free Online Tool

Base64 is an encoding scheme that converts binary data into ASCII text format. It is widely used for encoding data in emails, storing complex data in JSON, embedding images directly in HTML/CSS, and passing data through URLs. Our tool lets you encode any text to Base64 or decode any Base64 string back to plain text — all in real time, directly in your browser.

Common Use Cases for Base64

Base64 encoding is used in JWT tokens (the header and payload are Base64 encoded), data URIs for embedding images in HTML, email attachments (MIME encoding), API authentication headers (Basic Auth), and storing binary data in databases that only support text. Decoding Base64 is essential when inspecting JWT tokens, debugging APIs, or reading encoded configuration values.
