Do I need to include the data:image prefix?

No. The tool accepts both full data URIs (data:image/png;base64,...) and raw Base64 strings. When a raw string is entered, the tool attempts to auto-detect the image type.

What formats can be decoded?

Any image format that browsers support natively: PNG, JPEG, GIF, WebP, and SVG. The browser renders the decoded image, so format support depends on your browser version.

Can I download the decoded image?

Yes. A download button saves the decoded image in its detected format. The filename is base64-image.png (or .jpg, .gif etc.) unless you specify a custom name.

Where do I find Base64 image strings to decode?

They appear in HTML img src attributes (src="data:image/..."), CSS background-image data URIs, JSON API responses containing image data, and export files from some design tools and email clients.

Base64 to Image Converter

Decodes Base64-encoded data URLs and renders the image for preview and download. Accepts both full data URIs (data:image/png;base64,...) and raw Base64 strings (auto-detects format). Shows the image dimensions, file type, and estimated file size. Download the decoded image as its original format.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste a Base64 data URL or raw string to preview and download the encoded image. To encode an image to Base64, use the Image to Base64 converter.
