Why use this Base64 to Image converter
Real type detection
The file type comes from the decoded bytes, not the label, so mislabeled data URIs still download correctly.
Forgiving input
Data URIs, raw Base64, URL-safe Base64, line breaks and missing padding are all accepted.
Instant preview
See the image and its dimensions before downloading.
Private
Decoding happens entirely in your browser, which is safer for screenshots and tokens from logs or APIs.

Frequently asked questions
How do I convert a Base64 string to an image?
Paste it into the box above. If it's a valid image, a preview appears instantly and you can download it with the correct extension.
Do I need the data:image/… prefix?
No. Both full data URIs and plain Base64 text work. Without the prefix, the type is detected from the file contents.
What if the Base64 isn't an image?
You can still download the decoded file. PDFs are detected automatically; other types download as a .bin file.
Are my files uploaded to a server?
No. Conversion runs entirely in your browser via client-side JavaScript, on your own device. Your files never touch a remote server and nothing is stored, so it's a secure, private, no-upload tool for personal photos and confidential data, and it keeps working on slow connections.
