Client-Side vs Cloud Processing

Feature PDFTeq (Client-Side) Traditional Cloud Tools
Privacy Files stay on your device Uploaded to third-party servers
Processing Speed Instant (No upload required) Depends on internet speed
File Limits Limited only by device RAM Strict MB limits enforced
Data Security Impossible to intercept Vulnerable to server breaches

* Note: A select few tools (like Compress PDF) require server-side rendering using Ghostscript. These exceptions are clearly labeled on their respective tool pages. For client-side processing, we utilize the open-source pdf-lib library.

Frequently Asked Questions

A client-side PDF tool processes your document directly in your browser's memory using JavaScript and WebAssembly technologies. This means your private files are never uploaded to our servers, ensuring maximum privacy and security for sensitive documents like contracts or bank statements.

You can merge PDFs securely using a local-processing tool like PDFTeq. When you select files on our Merge tool, they are stitched together directly on your device. Since there is no upload step over the network, your data cannot be intercepted or stored by a third party.

Yes, PDFTeq tools are 100% free forever. Because most of our tools utilize your device's processing power rather than ours (client-side execution), our server costs remain incredibly low. This allows us to offer these professional utilities without requiring sign-ups, subscriptions, or adding watermarks.
