What is Base64 to Image Converter?
Base64 is a text encoding scheme that converts binary data like image files into a string of ASCII characters. When images are embedded in HTML, CSS, JSON, or APIs as Base64 strings or Data URIs, you may want to extract and view them as real image files.
A Base64 to Image converter decodes that text string back into a visual image you can preview, inspect, and download. Common searches include base64 decode image, data uri to image, base64 to png, base64 to jpg, base64 image viewer, and base64 image decoder online.

Base64 String vs Data URI — What's the Difference?
Raw Base64 String
Plain encoded text with no prefix, for example iVBORw0KGgo.... This is the format returned by many APIs and backend systems when they encode image data.
Data URI
A Base64 string with a MIME type prefix, for example data:image/png;base64,iVBORw0KGgo.... This is what browsers use natively as an image src or CSS url().
Both formats are supported. If you paste a raw Base64 string without a prefix, PNG is assumed by default. The format is auto-detected from the Data URI MIME type when a prefix is present.
When Would You Need Base64 to Image?
- Inspecting Base64-encoded images stored in a database or JSON response.
- Debugging API payloads that include embedded image data.
- Extracting an image from HTML or CSS that uses inline Data URIs.
- Recovering an image from a Base64 string in a config or code file.
- Previewing email attachments encoded as Base64 before decoding manually.
