Base64 to Image — Free Online Tool

About the Base64 to Image

Paste a base64 string or data URI and instantly preview and download the original image. Handy when code samples embed pictures.

Everything runs in your browser — nothing is uploaded.

Paste the long string from a stylesheet and save it as a normal image file you can open and edit.

Useful when a template is full of encoded blobs and you need to know whether one is an image, an icon or a font.

If a remote image fails to render, decoding it locally shows whether the data itself is damaged or just the markup around it.

A data URI carries a declared type at the start. If the preview stays blank, check that the type matches the actual bytes.
Very long strings may be truncated by the browser or the field you paste into — a few hundred kilobytes is already unusual.

Will this work with a raw base64 string?

Yes — wrap it automatically as image data. Any base64 that represents an image works.

Is my data private?

Yes, decoding happens entirely in your browser.

Why will my base64 not preview?

The three most common causes are a truncated string, a missing data URI header, or a declared type that does not match the actual file.

Can base64 hide something dangerous?

It is an encoding, not encryption. Anything encoded can be decoded by anyone, so never treat it as a way to protect a secret.
