==> Launch the Adobe Photoshop software
==> Click "File" > "Open" to select the photo you want to use
==> Double click on the background layer to create a new layer from it
==> Select the "elliptical marquee tool"
==> Use the tool to make a selection on the photo i.e draw circle on the photo
==> Once satisfied, right-click and click 'layer via copy"
==> Hide the first layer by clicking on the eye icon next to it
==> The round photo should now be visible
==> Click "File" > "Save as.."
==> Save as PNG file format as this will make it transparent i.e it will blend with any background
I hope it works for you.
