Why Browser-Based PDF Tools Are Safer for Confidential Files

Most online PDF tools upload your files to a server. Learn how in-browser processing keeps client and personal documents on your own computer.

Many popular PDF websites work by uploading your file to their servers, processing it there and sending the result back. For personal documents that may be acceptable, but for client records, financial statements, identity documents and contracts it means a copy leaves your control.

How this site is different

Every tool on this site runs inside your web browser using open-source libraries. When you choose a file, it is read by your own computer, processed in memory and the result is saved straight back to your downloads folder. The file is not sent to any server.

How you can check

• Load a tool page, then disconnect from the internet: the tool still works.
• Open your browser's developer tools, go to the Network tab and run a tool: no upload request is made with your file.

What is still stored

Your browser may remember small preferences on your own computer, such as your theme, recently used tools and the firm details you typed into the certification stamp. You can clear these at any time by clearing this site's data in your browser settings.
