Q:Are my private files saved to a server?

Absolutely not. All processing happens locally in your browser. No files are ever uploaded, ensuring 100% privacy.

Q:Why does it slow down when merging large PDFs?

Since processing relies on your browser memory, very large PDFs or high-resolution images (>50MB total) may consume high CPU resources. We suggest processing in smaller batches for optimal performance.
