Frequently asked questions
Does this work with any Base64 image string?
It works best when your string already includes a data: prefix. If it doesn't, the tool assumes it's a PNG and prepends data:image/png;base64, itself — so a raw JPEG or GIF string pasted without its own prefix may fail to preview correctly.
What filename does it download as?
Always image.png, even if the string you pasted was actually a JPEG or another format with its own data:image/... prefix.
Is my Base64 string sent anywhere?
No — it's decoded and rendered directly in an img tag in your browser, so nothing is uploaded to a server.
