How PDFSphere Processes Your Files
Different tools use different processing methods. Look for the badges on each tool.
Private Browser Processing
Many of our PDF tools process files directly in your web browser (e.g., Merge, Split, Watermark, PDF to Text). With these tools, your files do not need to be uploaded to PDFSphere's servers. Processing happens locally on your device for maximum privacy.
Secure Server Processing
Advanced tools, like document conversion (Word/Excel) and PDF unlocking, require server-side processing. When using these tools, your selected file is securely transmitted to our server for processing. Temporary files are discarded immediately after processing.
