Question 1

Which image formats are supported?

Accepted Answer

You can convert PNG, JPG, JPEG, WEBP, GIF, and SVG images to Base64, and decode any valid Base64 image string back into an image.

Question 2

Is anything uploaded to a server?

Accepted Answer

No. Files are read and converted entirely in your browser using the FileReader API. Nothing you upload or paste is sent to or stored on a server.

Question 3

What happens if I paste an invalid Base64 string?

Accepted Answer

The tool validates the string by attempting to render it as an image. If it is corrupted or not a valid image format, a clear error message is shown instead of breaking the page.
