Magic lasso tool
It does contain a checkerboard, not transparent pixels.

Therefore, it is necessary to increase the tolerance of the Magic Wand tool to make sure that the pure white and near white pixels are selected. However, in the original image, the background is not pure white, particularly near the edges of the green and black object. In this case, it would only select all pure white pixels if you clicked on the background color. Tolerance level of the Magic Wand tool: If you set the tolerance level of the Magic Wand tool to zero, it will only select the exact color of the pixel you click on.Presumably, his background color was the default color of white. I assume this is what happened to wchettel when he said that after trying my method, nothing changed. If you select and delete pixels from a background layer, the deleted pixels will be replaced with the color of the background color swatch.sorry for not including this step in my reply, Walter.) So, it was not necessary for me to convert the layer. (When I copied startingtopuff's original image from the forum webpage and used the File>New>Image from Clipboard command in the Editor to edit it, only a regular image layer was created.As Phinny said, you can double-click on a background layer to convert it. Therefore, it is necessary to convert it to an ordinary layer.

A background layer cannot have transparent pixels. after opening the original file in the PSE Editor, it probably has a single background layer.Presumably, the original image file is in a format that does not support transparency, e.g. startingtopuff has an image/logo/object on a white background and wants to remove the background so the image/logo/object appears on a transparent background.Just to summarize this thread for future viewers, to clarify some confusion that I introduced, and to answer some remaining questions, here are the main points:
