Choose Image → Base64 to encode a file, or Base64 → Image to turn a string back into a picture.
STEP 2
Add your image or text
Drop an image to get its data URL, or paste a Base64 / data URL to decode it. It all stays on your device.
STEP 3
Copy or download
Copy the data URL, the <img> tag or the CSS snippet — or download the decoded image. Nothing is uploaded.
