How do I turn a Base64 string back into an image?

Paste the Base64 text into the box. The decoded image appears right away in the preview, and you can click Download to save it to your device. There are no extra steps.

Do I need the data:image prefix on my string?

No. The tool accepts a full data URI that starts with data:image/png;base64, as well as a plain Base64 string with no prefix. Either form decodes the same way.

Is it safe to decode private images here?

Yes. Decoding happens locally in your browser, so the Base64 text and the resulting image never leave your device and nothing is sent to a server.

What the Base64 to Image tool does

This tool takes a Base64 string and turns it back into a real, viewable image you can save. Developers often store images as Base64 text inside HTML, CSS, JSON, config files, or API responses, but that text is impossible to read with your eyes. Paste it here and the picture appears instantly, so you can confirm an embedded logo is correct, recover an icon from a code snippet, or pull an image out of a database dump. Front-end developers, email coders, QA testers, and anyone who has run into a long data:image string will find it handy.

How to use it

Copy your Base64 string, with or without the data:image prefix.
Paste it into the text box. The decoded image shows up in the preview automatically, with no button to press.
Check that the preview looks right.
Click Download to save the decoded file to your device.

A quick example

Say you have a string that begins with data:image/png;base64,iVBORw0KGgo and continues for hundreds of characters. Paste the whole thing in and a PNG appears in the preview, ready to download. A bare string without the prefix works too, since the tool detects the format from the decoded data. If nothing shows up, the text is usually truncated or has stray spaces or line breaks, so paste the complete string again.

It all runs in your browser, so your data stays private. The tool is free, needs no sign-up, and works on any device.
