🔒 Privacy
Your PDF is processed locally in your browser. Files are not uploaded to our server, and the original PDF remains untouched.
⚠️ Important Notes
Complex PDFs may not render exactly as expected after resizing. Password-protected or corrupted PDFs may fail. Fill/crop can intentionally crop content, and very large PDFs may require more browser memory.
