Batch Export Layers

A simple script that exports every layer in the active document as a separate PNG file, named after the layer.

Usage

1. Open your Affinity document
2. Run the script from File > Scripts > Run Script
3. Choose an output folder
4. Each layer will be exported as <layer-name>.png

The Script

const doc = app.activeDocument;
if (!doc) {
  alert('No document open');
  exit;
}

const folder = Folder.selectDialog('Choose export folder');
if (!folder) exit;

for (const layer of doc.layers) {
  const filePath = new File(folder.fsName + '/' + layer.name + '.png');
  const opts = { dest: filePath, type: 'png', quality: 100 };
  layer.rasterize(opts);
}

alert('Exported ' + doc.layers.length + ' layers.');

Notes

• Nested layers are not recursively exported — only top-level layers.
• Adjust the type in opts to export as jpg, pdf, etc.
• Add error handling for production use.
