How It Works
In encode mode, drop an image file and the tool instantly converts it to a Base64 data URI using the browser's FileReader API. Copy the full data URI (with MIME prefix) or the raw Base64 string.
In decode mode, paste a Base64 string or data URI and the tool renders the image for preview and download. No server required — everything runs in your browser.
