Decoding Base64 Images

Base64 encoding is frequently used by developers to embed image data directly into HTML, CSS, or JSON payloads, reducing the number of HTTP requests required to load a page. This tool allows you to paste a raw Base64 string and instantly visualize the hidden image, making debugging much easier.

Format Compatibility

This decoder automatically handles strings whether they include the Data URI scheme prefix (e.g., data:image/png;base64,) or if they are just the raw, raw Base64-encoded bytes. If the prefix is missing, it will attempt to decode it as a standard PNG.
