Frequently Asked Questions
What input does this accept?
You can paste a full data URL (data:image/png;base64,...) or a raw Base64 string. The tool detects the image type automatically from the Base64 content.
How is the image type detected?
The first characters of a Base64 string reveal the format: /9j/ is JPEG, iVBOR is PNG, R0lGOD is GIF, UklGR is WebP, and Qk is BMP.
Can I download the decoded image?
Yes. Once the preview appears, click Download and the image saves in its detected format.
Is my data sent anywhere?
No. Decoding happens entirely in your browser. Your Base64 string never leaves your device.
