Frequently Asked Questions
1. Do I need to include the 'data:image/...' prefix?
No. If you paste a raw Base64 string without a prefix, our tool will automatically attempt to add data:image/png;base64, for you. However, including the full Data URI ensures the correct file extension and MIME type are used.
2. Is my Base64 data sent to any server?
No. All decoding and image generation happens entirely in your browser. Your Base64 string never leaves your device, making it safe to decode private images or sensitive internal data.
3. What image formats are supported?
The tool supports all standard image formats including PNG, JPEG, WebP, GIF, and SVG. As long as the Base64 string is correctly encoded, the browser will render it.
4. Can I convert the image back to Base64?
Yes! Use our companion tool, Image to Base64, to perform the reverse operation. Both tools work client-side to keep your data private.
