Collage Bench

A layered PNG editor with reversible cropping, undo history, and a registry for adding tools after review.

01 / Editing

Preserve the source pixels.

  1. 01Insert a PNG as a layer
  2. 02Move and resize the selection
  3. 03Apply a reversible crop
  4. 04Undo or restore the crop
  5. 05Save the layered project
  6. 06Export a flattened PNG

The editor uses a native WebView2 window. Autosave and project files preserve the document, while PNG export produces the finished composite.

02 / Extension

A new tool enters through one registry.

Selection, insertion, and cropping follow the same registered-tool contract. A review request can become an isolated tool with shared document mutations and undo commands, instead of a rewrite of the canvas.
