Base64 to Image Converter - Decode Data URIs and Save the File

What Base64 to Image Does

This tool takes the text form of an image and gives you the file back. Base64 is a transport encoding: it rewrites arbitrary bytes using only the 64 characters A-Z, a-z, 0-9, plus and slash, so that binary data can travel through places that only accept text. Wrapped in a data URI — the `data:image/png;base64,` prefix followed by the payload — it can sit directly inside an HTML attribute, a CSS url(), a JSON field or an email body. Decoding reverses that mapping exactly, so the bytes you get back are the bytes that went in, down to the EXIF block and the colour profile. Before anything is shown, the tool cleans the input: it finds the payload even when it is buried inside a full `img src="…"` tag or a `background-image: url(…)` declaration, drops the line breaks and indentation that a code formatter added, and strips wrapping quotes. It then identifies the format from the first bytes of the decoded data — the PNG signature 89 50 4E 47, the JPEG marker FF D8 FF, the GIF87a/GIF89a header, the RIFF/WEBP container, the ftyp box of AVIF, or an opening `svg` tag. The MIME type written in the prefix is only a claim: it is ordinary text that a generator can get wrong and anyone can edit, so it is displayed for reference but never used to name the download. Everything happens in the page, on your device; the string is not sent anywhere.
