Image to Base64

Convert an image into a Base64 string or data URI to embed directly in HTML, CSS or JSON. In your browser.

How to use it

  1. 1
    Add an image

    Drop a file, paste, or tap to pick from your device.

  2. 2
    Copy the Base64

    The full data URI appears — copy it, or toggle off the prefix for raw Base64.

  3. 3
    Nothing is uploaded

    The whole thing runs in your browser. Close the tab and every trace of your image is gone — there is no server that ever sees it.

Embed images without a file

Base64 lets you inline an image directly in HTML, CSS or a JSON payload, avoiding a separate file request. Handy for small icons, email templates and quick prototypes.

Drop an image and copy the string. It's encoded in your browser, so even private assets stay local.

Frequently asked questions

What's the difference between the two options?+

The data URI includes a data:image/...;base64, prefix so browsers can render it directly. Raw Base64 is just the encoded bytes, for when you add the prefix yourself.

Is my image uploaded?+

No. Encoding happens in your browser.

Any size limit?+

Very large images make very large strings, which can slow down pages. Base64 is best for small images.
