When you need PNGs in one PSD
Photoshop opens a PNG as a document with a single layer, so ten PNGs means ten separate documents. These are the usual reasons to want them stacked in one file instead:
- Character parts for Live2D or Spine. Parts drawn or exported as separate PNGs, all the same size, need to be one PSD with one layer per part. Leave the placement on top left so every part stays where it was drawn. The Live2D guide covers the rest of the rules.
- Print and merch files. A print shop asks for a layered PSD and you have the artwork, the text and the background as separate PNGs.
- Asset packs and mockups. Sprites, stickers or design elements that a buyer or teammate wants to edit in one place.
- Layers exported one by one. Apps that export each layer as its own PNG, such as Procreate’s Share Layers > PNG Files, give you a folder of images. This tool puts them back together.
If you have the original .procreate file, the Procreate converter is the better route: it keeps blend modes, opacity, groups and masks, which separate PNGs don’t carry.
How the layers are built
| Part of the PSD | What you get |
|---|---|
| Layer order | The list order, top first; reorder before saving |
| Layer names | The file name without .png |
| Transparency | Kept per layer, including soft edges |
| Canvas | Widest image by tallest image |
| Smaller images | Centred, or at the top left |
| Background | None (transparent) or a white layer named Background |
| Resolution | 72, 150 or 300 dpi stored in the file; pixels unchanged |
| Large canvases | Saved as PSB above 30,000 px on a side |
| Blend modes | Normal at 100% opacity for every layer |
The PSD is 8 bits per channel RGB, which is what PNG and JPG files hold and what every app here opens.
Doing it in Photoshop instead
If you have Photoshop, it has a built-in way: File > Scripts > Load Files into Stack, then pick the PNGs. It makes one document with a layer per file, the same idea as this tool. GIMP has File > Open as Layers, and Photopea lets you drag several images into an open document. This page is for when you don’t have those apps at hand, or want it done in a few seconds on any computer.
