Product Image Background Removal

I have between one and ten product photos that need their backgrounds removed cleanly so the items sit on a fully transparent canvas. Please keep every edge crisp, retain natural shadows where appropriate, and deliver each file as a high-resolution PNG (original dimensions). My only goal is to receive ready-to-use, transparent product images that slot straight into my catalogue and website without any visible artefacts or halos. If you use Photoshop, remove.bg, or any other tool is up to you—as long as the final cut-outs look seamless. Once approved, supply the layered PSDs or editable files alongside the PNGs so I can make minor tweaks later if needed.
