Moving the headline on a finished poster, removing an object or recoloring the background usually needs the layered source file. Without it, you cut out every element by hand and paint in whatever was behind it.
Seedream 5 by ByteDance does that for you: it finds the separate elements in the picture, puts each one on its own transparent layer and fills in the background behind them. You get up to 16 layers with readable names like "Headline", "Woman in jacket" or "Logo".
The layers open in an editor right on the site. Hide them, drag them with the mouse or arrow keys, and change their order. Download the result as a flat PNG, a PSD for Photoshop or Photopea, or a ZIP with every layer as its own PNG. To pull out something specific, say so in the prompt field.
