No. All PDF merging and splitting happens inside your browser using PDF.js and the PDF-Lib library. Your files never leave your device.
There is no enforced limit since processing happens in the browser. Merging very large PDFs (>100MB total) may be slow on low-memory devices.
You need to unlock password-protected PDFs before merging. This tool supports unprotected PDFs.
