    Why this image tool is private

    Base64 encoding is pure text manipulation of bytes already in memory. It needs no network connection, and your image is never transmitted to produce the string.

    Other tools in this category upload your file to a server, process it in the cloud, and return a download link. That means your document sits on someone else's disk — often with a retention window measured in hours. Here, the file is read by your browser, transformed in memory, and saved straight back to your disk. You can watch it happen in the live check above: the counter for files uploaded stays at zero.

    Frequently asked

    What is a Base64 data URL?
    A way of writing a file as text. It begins with data: followed by the file's media type and the encoded bytes. You can paste it where an image URL would normally go in HTML or CSS.
    Should I embed large images this way?
    No. Encoding increases size by roughly a third, and the text cannot be cached separately. It suits small icons and logos; anything larger is better served as its own file.
    Will it work in a CSS background property?
    Yes. Wrap the data URL in url() as you normally would, including the quotes. That is the most common use, avoiding an extra request for a small decorative image.
    Is the output safe to share?
    Treat it exactly like the image itself. Anyone holding the string can reconstruct the picture, so it offers no protection or obfuscation.
