Base64 to Image

Base64 to Image

The Base64 to image tool renders a Base64 or data-URI string as an actual image you can preview and download. When you have an inline image embedded in CSS, an HTML <img> tag, a JSON response, or a data URI, it can be hard to tell what it actually depicts. Paste the string here and see the picture immediately, then save it as a file if you need it.

How it works

Decoding happens entirely in your browser using JavaScript. The tool accepts both raw Base64 and full data URIs like data:image/png;base64,..., detects the format, and paints the result onto the page. Because rendering is local, even large images decode without any upload, and the picture never touches a remote server.

Practical use cases

• Preview an inline image pulled from CSS, HTML, or an API payload.
• Download an embedded data URI back to a real PNG, JPG, or GIF file.
• Verify that a Base64 blob is a valid, non-corrupt image.
• Inspect favicons, icons, or thumbnails stored as strings.

To create Base64 from a file in the first place, use Image to Base64. For plain text strings, the Base64 Encode / Decode tool covers encoding and decoding, and the URL Encode / Decode tool helps when data URIs are wrapped in URL encoding.

Private by design

Your image data is decoded in-browser and never uploaded. The tool is free, needs no account, and works on all modern browsers including mobile, so you can preview and download images from Base64 while keeping them entirely on your device.
