Do I need to include the `data:image/png;base64,` prefix when pasting?

No! You can paste either the complete Data URL (with the `data:image/...;base64,` prefix) or just the raw Base64 characters (`iVBORw0KGgo...` for PNG, `/9j/4AAQSkZJRg...` for JPG). If the prefix is missing, the tool wraps the string automatically so the browser can decode it.

How can I tell what image format a raw Base64 string is from its first few characters?

Base64 file headers (magic bytes) have recognizable prefixes: PNG files always start with `iVBORw0KGgo`, JPEG files start with `/9j/`, GIF files start with `R0lGOD`, and WebP files start with `UklGR`.

Why does my Base64 image fail to load or appear cut off?

This almost always happens when the string was truncated by a console log buffer or copied partially. Check that you copied the complete string all the way to the end (often ending with `=` or `==`).

Can I convert the downloaded image into WebP or JPG?

Yes! Download the decoded image and open it in our Convert Image or WebP Converter tool.

Is the decoded image private?

Yes. The Base64 string is decoded locally by your browser's native image decoder and never leaves your device.
