Base64 to Image
Paste a raw Base64 string and a MIME type, and get a preview plus downloadable image file.
Paste your raw Base64 string and choose the correct MIME type - this tool decodes it into a viewable, downloadable image, entirely in your browser.
If you already have a full data URI (with the data: prefix) rather than raw Base64, use the Data URI to Image tool instead - it doesn't need you to specify the MIME type separately.
What Does This Tool Do?
It takes a raw Base64 string (without a data URI prefix) plus a MIME type you specify, reconstructs the data URI internally, and decodes it into a real, downloadable image file.
Why Use This Tool?
Useful when you have raw Base64 image data from an API response or database field that doesn't include the MIME type/prefix, and need to actually view or save it as a file.
How to Use It
- Paste the raw Base64 string.
- Select the correct image MIME type (PNG, JPEG, GIF, WebP, or SVG).
- Review the preview and download the image file.
Common Errors
If the preview doesn't render, the most common cause is selecting the wrong MIME type for the actual encoded data - try the other common image types if the first guess doesn't work.
