// BASE64 TO IMAGE · ABOUT THIS TOOL
About the Base64 to Image
Base64 image strings turn up everywhere: API responses, database fields, CSS files, email source. This converter turns them back into viewable images right in your browser, detecting the genuine format from the file signature.
It handles messy pasted strings too: data URL prefixes, stray whitespace, line breaks and URL-safe alphabets, with honest error messages when the bytes are not an image.
Where it helps most
Seeing the picture behind the string.
Checking API responses
Frontend engineers use it to check what an API actually returned before wiring it into a page. Paste the string, see the picture, move on.
Email signatures
Email developers verify that embedded images in HTML signatures render correctly. A quick paste beats rebuilding the whole signature to check one image.
Debugging CSS assets
People debugging CSS spot-check whether an encoded asset is the right file. No need to decode it by hand or write a throwaway script.
Mystery blobs
Anyone who received a Base64 blob in a chat or document can see the picture instantly. No script, no tooling, just paste and preview.
Decoding, simplified
Paste it, see it, download it.
Data URIs accepted
It accepts both full data URIs and bare Base64 strings, so you do not have to strip prefixes yourself. The format is detected from the header automatically.
Format auto-detected
The page reads the data and detects the image format from the header, rendering a live preview. The reconstructed PNG or JPG downloads with one click.
Safe for sensitive strings
The decoding is done with plain JavaScript in your browser, so the string never travels to a server. That matters for scanned documents or internal screenshots.
Base64 to Image: private by design
Decoding happens with plain JavaScript in your browser. Nothing to install, no account, instant on paste.
Base64 to Image FAQs
Paste either a full data URI (starting with data:image/...) or a bare Base64 string. The tool detects the format from the header, renders a preview of the image and gives you a download button.
