Since PSD isn't an open format ... great alternative if you need to edit a PSD file and don't have Photoshop experience. If you've never heard of Photopea before, you're in for a treat.

To get started with Photopea, select whether you want to create PSD file or image or edit. According to your requirement, press either Ctrl+O or Ctrl+N. It is also possible to open a file from a URL.
