Base64 to Image — Decode a Data URI to an Image

Runs in your browser — your files never leave your device

Paste a Base64 string or a full data URI to preview the image and download it — entirely in your browser. Nothing is uploaded.

How to use it

  1. 1
    Paste the Base64

    Paste a raw Base64 string or a full data: URI into the box.

  2. 2
    Preview

    The decoded image appears instantly if the data is valid.

  3. 3
    Download

    Download the image to your device.

From data URI back to a file

If you have an image encoded as Base64 — from a data URI in some CSS, an API response, or a config file — this turns it back into a viewable, downloadable image. Both raw Base64 and full data URIs are accepted.

Frequently asked questions

Is my data uploaded to a server?

No. Decoding and preview happen entirely in your browser; nothing is sent anywhere.

Do I need the data: prefix?

No. You can paste a full data URI or just the raw Base64 — raw Base64 is assumed to be a PNG.

Why does my image not show?

The Base64 may be incomplete or not an image. Make sure you copied the whole string.
