How Omni PDF tools work
Every tool runs in your browser using your device's CPU. When you pick a PDF, it never leaves your machine during processing. The output file is generated locally and downloaded directly to your device.
For large documents, processing time depends on your device. Modern phones and computers can handle typical office PDFs without issues. You can always cancel a running operation.
