Base64 to Image

A Base64 to image decoder takes a Base64-encoded string, usually a data URI, and turns it back into a viewable, downloadable image file. Base64 is a way of representing binary data as plain text, which is how images get embedded in HTML, CSS, JSON, and emails; this tool reverses that, reconstructing the original PNG, JPG, GIF, or WebP. It reads the MIME type from the data URI prefix, for example data:image/png;base64, to know which format to rebuild, then decodes the text in your browser and renders a live preview so you can confirm it is correct before downloading. The most common stumbling block is the prefix. A complete data URI includes the data:image/...;base64, header, but raw Base64 copied from an API response or a database often lacks it. If your string starts straight into characters like iVBORw0KGgo (a PNG) or /9j/ (a JPEG) with no header, the format cannot be auto-detected reliably, so paste the full data URI when you can. Another frequent issue is stray whitespace, line breaks, or URL-safe characters: data copied from JSON or logs may contain newlines or be URL-encoded, which can break decoding until cleaned up. Decoding locally matters for privacy because Base64 blobs sometimes carry sensitive content like scanned documents or signatures, and this tool never uploads them. Typical uses include verifying what an API actually returned, extracting an image a developer embedded in code, debugging a data URI that will not render, and saving an inline image as a normal file. Everything runs in your browser and works offline once the page has loaded.
