We are always looking for ways to add value to the Lighthouse Hub, and this one is a win for anyone who works with PDFs regularly. We have added a full-featured, secure PDF toolkit to the Hub, and it is available now!
What Is It?
This is a comprehensive suite of browser-based PDF tools. What makes it stand out is its approach to privacy: your files never leave your device. All processing happens client-side, right in your browser, with no uploads to a third-party server, and no file size tricks or paywalls.
We licensed it commercially so our clients have a clean, trusted access point through the Lighthouse Hub.
Why This Matters for Your Team
Everyday PDF tasks, like combining invoices, redacting sensitive info before sharing, signing a form, or trimming a scanned document, usually mean opening a desktop app, paying for an online tool, or sending files to a service that stores your data. This removes all of that friction.
Because everything runs in your browser locally, it is also a smart choice when handling documents with sensitive business information. Nothing gets transmitted, nothing gets stored.
