Frequently Asked Questions

What happens if my Base64 string is invalid?
The tool will show an error message and no preview image will be displayed.
Does this tool upload the image anywhere?
No. The conversion and preview happen entirely inside your browser.
Can I download the converted image?

Will this work with different image types?
Yes, especially when the input already includes the correct data:image/… prefix.
