Free Online Base64 to Image

1. Paste a data URI or a raw Base64 string into the text box.
2. Click Decode to reconstruct the image.
3. Preview the result and confirm the detected format and size.
4. Click Download image to save it as a real file.
5. Use Clear to start over with a new string.

Images stored in databases, returned by APIs, or embedded in HTML are often encoded as Base64 text. To use them outside that context you have to decode them back into a real binary image file. This tool reverses the encoding and reconstructs the picture.

It accepts a full data URI (data:image/png;base64,...) and reads the MIME type from the header so the download gets the correct extension. If you paste raw Base64 with no header, it assumes PNG. The decoded image is rendered in an <img> element for an instant preview before you save.

Decoding happens entirely in the browser — the data URI is handed straight to the image element and turned into a downloadable blob locally. Nothing is uploaded, so tokens and private images you paste never leave your machine.
