Turn a Base64 string back into an image
Images are sometimes stored or transmitted as Base64 text — inside JSON, a data URI, or a config. To actually see or save the picture you need to decode it back into a file. This tool takes a Base64 data URI and reconstructs the image in your browser, ready to preview and download.
How to use it
- Paste the Base64 string or full data URI.
- Preview the decoded image.
- Download it as a normal image file.
When you'll need it
- Extracting an image embedded in a JSON payload.
- Saving an inline data-URI graphic as a real file.
- Checking what a Base64 blob actually contains.
Questions people ask
It won't decode — why? The string may be incomplete or missing its data-URI prefix. Make sure you've copied the whole value.
Is my data uploaded? No — decoding happens locally in your browser.
