CLC PDF Layer Stitcher

Upload or drag-and-drop a layered sewing-pattern PDF anywhere on the screen, choose the layers/sizes to keep, preview the result live, then download a new flattened PDF with unselected layers left out.

1. File and output setup

You can also drag and drop a PDF anywhere on the screen. All processing happens in this browser. No upload to a server is needed.
Leave blank to use all pages. Enter 0 anywhere in the range to insert a blank page at that point.
Trim removes the amounts below from each source page before the pages are joined.
This crops the finished stitched sheet. In separate-pages mode it crops each final page.
Adds an equal white margin around all four sides of the finished stitched sheet. Used in stitched-sheet mode only.
Enter the name only. The app will add .pdf automatically if needed.

2. Layers / sizes

Load a PDF to detect layers.
No PDF loaded yet.
Download output is flattened from the visible layer result, so unselected layer artwork is not carried into the new PDF. The trade-off is that the final file is image-based rather than editable vector paths.
