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.
Is there a file size or page limit?
No. Because nothing is uploaded, there are no server-side caps — the only limit is your device's memory, which handles even thousand-page documents.
