Questions

Are my files uploaded?

No. CommandEditor runs entirely in your browser with WebAssembly — your file never leaves your device. You can verify it: open your browser's network inspector, or switch off Wi-Fi after the page loads; the tool still works.

My page count isn't a multiple of 4?

Blank pages are inserted automatically at the right spots so the imposition folds correctly.
