How to decode Base64 into an image
- Paste raw Base64 or a complete image data URL.
- Decode and inspect the preview, detected format, dimensions, and byte size.
- Download the restored image using its detected file extension.
What Base64 decoding does
Base64 maps groups of text characters back to their original binary bytes. The tool uses the data-URL MIME type or a common file signature to identify the image, then creates a temporary browser URL for preview and download.
FAQ
What Base64 formats can I paste?
Paste raw Base64 characters or a complete data URL such as data:image/png;base64,... A data URL provides the most reliable file-type information.
Which image types can be detected?
The decoder recognizes common PNG, JPG, GIF, WebP, and SVG signatures. Other image data URLs may work when their MIME type is included.
Does decoding reduce image quality?
No. Base64 decoding restores the original bytes; it does not resize, recompress, or otherwise alter the image.
Why does Base64 look larger than the image file?
Base64 represents binary bytes using text characters and normally adds roughly one-third to the data size before any surrounding markup.
Why might valid Base64 fail to display?
The decoded bytes may not be an image, the MIME type may be wrong, the payload may be incomplete, or the browser may not support that image format.
