Base64 to Image Converter
Free Base64 to image converter — paste a Base64 string or data URI to preview and download the original PNG, JPEG, GIF, WebP or SVG, entirely in your browser.
Runs entirely in your browser — nothing you enter is uploaded or stored.
Turn a Base64 string back into an image
Paste a Base64 data URI or a raw Base64 string and this tool rebuilds the picture so you can preview and download it. It is the reverse of the Image to Base64 tool — useful when you find an inlined image in CSS, JSON or an API response and need the actual file.
If your string has no data: prefix, choose the matching image type from the dropdown. Decoding and preview run entirely in your browser via a data URI — nothing is uploaded, and the Download button saves the file straight from memory.
Frequently asked questions
What input does this accept?
Paste either a full data URI (data:image/png;base64,iVBORw0…) or just the raw Base64 string. If you paste raw Base64 without a prefix, pick the correct image type from the dropdown so the browser can render and download it.
How do I save the decoded image?
Once the preview appears, click Download. The file is rebuilt from the Base64 in your browser and saved locally — nothing is sent anywhere.
Why does my image not preview?
The most common causes are a truncated Base64 string, extra whitespace or line breaks, or the wrong image type selected for a raw (prefix-less) string. Make sure you copied the entire string and choose the matching format.
Is my data uploaded?
No — decoding and preview happen entirely in your browser. Your Base64 never leaves your device, which you can confirm in the Network tab or our Content-Security-Policy.
