Encode text or files to Base64, or decode Base64 strings back to their original content. Generate data URIs for embedding. All processing happens in your browser.
What is Base64?
Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format. It is commonly used to embed images in HTML/CSS via data URIs, encode email attachments (MIME), transmit binary data in JSON APIs, and store binary content in text-based formats.
