Decoding happens on your device — nothing is uploaded.
Turn a CSS data URI back into a file
Developers often find a background-image set as an inline data:image/png;base64 URI in their CSS or HTML and need the original file back. Paste the whole data URI here and the image renders instantly, then download it as a real PNG or JPG. The tool reads the MIME type from the prefix, so you get the correct extension automatically.
Inspect a Base64 string from an API response
When an API or JSON payload returns an image as a raw Base64 blob, you can't tell what it is by reading the characters. Paste the string in to decode and preview it immediately and confirm it's the right asset, avatar, or QR code before wiring it into your app. No prefix needed; the tool assumes PNG when no image type is given.
Recover an image emailed as Base64 text
Sometimes an image arrives pasted as a long Base64 block in an email, chat, ticket, or shared document instead of as an attachment. Drop that text here to rebuild the picture and save it as a usable file. Decoding runs entirely in your browser, so sensitive screenshots or scanned documents are never uploaded to any server.
