About this tool
Base64 Encode runs entirely in your browser. Base64 Encode converts between raw data and Base64 in your browser, handling text or files locally.
Binary-safe handling means images and other files survive the round trip intact. Nothing you enter is uploaded, and it keeps working offline once the page has loaded.
