Base64 to Image Converter — Decode Base64 to Image Online

Paste a Base64-encoded string and see the image instantly. Auto-detects image format from data URI prefix, shows a live preview, and lets you download the decoded image file.

When You Need Base64-to-Image Conversion

Developers encounter Base64 images in API responses that return embedded image data, database records where images are stored as text blobs, email sources with MIME-encoded inline images, and HTML/CSS files containing data URI images that need to be extracted as files. This tool lets you paste the encoded string and instantly see and download the original image.

Format Detection

If your Base64 string includes a data URI prefix like data:image/png;base64,, the tool automatically detects the image format. If you paste just the raw Base64 without a prefix, use the MIME type dropdown to specify the format. The tool defaults to PNG, but you can select JPEG, GIF, SVG, WebP, or other formats as needed.

Completely Private

All decoding happens in your browser. The Base64 string is never sent to any server. This is important when working with proprietary images, user-uploaded content, or any image data that shouldn't leave your machine. Close the tab and the data is gone.
