Most PDF tools upload your sensitive documents to their servers. We take a fundamentally different approach.
| Feature | PDFScan Pro | Adobe | iLovePDF | Smallpdf |

| Client-side processing | ||||
| Files uploaded to server | Never* | Always | Always | Always |

* Client-side tools never upload files. Server-side tools (OCR, conversion) upload temporarily with 256-bit SSL encryption and auto-delete within 1 hour.
We use pdf-lib to process PDFs directly in your browser. No uploads, no servers, no risk.
Files NEVER leave your browser
Powered by pdf-lib: An open-source JavaScript library that runs entirely in your browser. Your PDF is loaded into memory, processed locally, and the result is downloaded directly -- no network requests involved.
Temporary processing with auto-delete
Files are encrypted during transfer using industry-standard TLS.
Processed files are automatically purged from our servers. No exceptions.
We never read, analyze, or store your documents for any purpose beyond processing.
OCR, PDF-to-Word, Excel/PPT conversion, and other format conversions require server processing.
Privacy is not a feature we bolt on. It is the foundation of everything we build.
We follow EU data protection regulations. You have full control over your data at all times.
We do not use tracking cookies or third-party analytics that follow you across the web.
Your documents and personal data are never sold, shared, or monetized. Period.
Client-side tools run in your browser. Server-side tools process temporarily and auto-delete within 1 hour.
Our Android and iOS app takes privacy further with on-device AI that works completely offline.
Google ML Kit text recognition runs entirely on your phone. No images are sent to any server.
Extractive text summarization happens locally. Your documents are analyzed without ever leaving the device.

The mobile app works fully offline. All scanning, editing, and processing happens on your device.
