How Your Files Stay 100% Private

Unlike most online PDF tools, your files are never uploaded to any server. Everything runs inside your browser tab using open-source JavaScript libraries.

Browser-Only Processing

PDF manipulation happens via pdf-lib and PDF.js, both running locally in your browser with no network requests during processing.

Zero Server Contact

After the page loads, your files never leave your device. No server-side code touches your documents.

Works Offline

Once the page has loaded, you can disconnect from the internet and the tools will continue to work.

Technical details: how it works under the hood

These tools use pdf-lib (an open-source library for creating and modifying PDFs) and PDF.js (Mozilla's open-source PDF renderer). Both libraries execute entirely within your browser's JavaScript runtime. File data stays in memory only for the duration of the operation, then is released for garbage collection. No cookies, local storage entries, or IndexedDB records are created from your document content.
