How do I make an image transparent?

Upload your image, then drag the opacity slider to the desired transparency level. The checkerboard pattern shows what areas are transparent. Click Apply and Download.

What does the background color do?

The background color fills the area behind the image in the preview. When you export as a non-PNG format (like JPEG), this color becomes the background since those formats don't support transparency.

Why should I export as PNG?

PNG preserves transparency. If you export as JPEG or other non-transparent formats, the background color will replace all transparent areas.

What is the checkerboard pattern?

The checkerboard pattern is a visual indicator that shows transparent areas. It is not part of the actual image - it just helps you see where the image is transparent.

Is my image uploaded to any server?

No. All image processing happens locally in your browser using the Canvas API. Your images never leave your device.
