How Cloud PDF Tools Handle Your Files
iLovePDF and similar cloud-based PDF tools require you to upload your documents to their servers for processing. Even with good intentions, this introduces real privacy and security risks.
- Your files are uploaded to remote servers before any processing begins
- Documents may be stored on their infrastructure for hours or longer
- Server-side processing means your data passes through third-party systems
- You cannot independently verify when or if your files are truly deleted
- Data breaches at cloud providers can expose your sensitive documents

- Zero file uploads — processing happens in your browser
- Verify privacy yourself by checking the Network tab in DevTools
- Works offline after the initial page load
