Base64 Encoder & Decoder

The Cybro Tools Base64 Encoder & Decoder is a fast, free online tool that converts text, data, and files to Base64 encoding or decodes Base64-encoded strings back to their original form, all processed directly in your browser without any uploads. Base64 encoding is essential for embedding binary data in text formats, transmitting data over text-based protocols, encoding API credentials, and embedding images in HTML/CSS. Our encoder supports full UTF-8 international character encoding, handles multi-line Base64 strings, and processes data of any size. The decoder accepts both standard Base64 and URL-safe Base64 variants. Additional features include real-time character count, line-wrapping options for email-compatible output, and a clean copy-to-clipboard interface. All processing happens locally using JavaScript's built-in encoding functions — your data never leaves your device.
