Base64 to Image
Decode Base64 strings back into viewable image files with this free online tool. It is perfect for developers debugging API responses or processing encoded data. Use it to extract and view images hidden in code or text payloads.
How the Base64 to Image works
- 1
Add Your Content
Paste a full data URI such as data:image/png;base64,... or just the raw Base64 payload; missing prefixes are completed automatically as PNG.
- 2
Process Your Data
The tool parses the string and decodes the ASCII characters back into binary image data. It processes the conversion entirely in your browser to render the image.

Get Your Results
View the decoded image in the preview area. You can download the file to your device or copy the clean image data for further use.

Base64 to Image FAQ
Do I need to create an account?
No, you can use this tool immediately without signing up or logging in.
Is my data secure and private?
Yes, all processing happens directly in your browser, so no data is ever sent to our servers.
Does it work offline?
Once the page is loaded, the core logic works offline since it runs locally in your browser.
Which image formats can be decoded?
Any format your browser can display when given a proper data URI, including PNG, JPEG, GIF, WebP, and SVG. Raw payloads without a prefix are treated as PNG.
What happens with invalid Base64 input?
A clear error message appears instead of a broken image, so you immediately know the string could not be decoded.
How is it different from similar tools?
Everything runs entirely in your browser as local JavaScript - there is no account step and nothing is uploaded.
What is the technical working principle?
It builds a data URI from your string and hands it to an Image element, letting the browser decode and render it entirely locally.
What is a common use case?
Frontend developers use it daily to preview and debug Base64 images received from backend APIs or database dumps.
