Lumin

Lumin is a browser-based PDF and document workflow platform designed to simplify how teams edit, share, and sign documents. It centralizes key tasks—such as annotating, reviewing, and approving PDFs—into a single, collaborative workspace. The tool is built to streamline document-heavy processes, from simple form filling to complex contract workflows, without requiring desktop software installations.

Core capabilities include in-browser PDF editing, form creation and completion, e-signatures, and real-time collaboration. Users can highlight, comment, add shapes and text, merge or split files, and insert images directly into PDFs. Lumin integrates with cloud storage platforms such as Google Drive, enabling easy access, sharing, and version control across teams. Audit trails, access controls, and signature tracking support compliance and transparency for organizations that need reliable documentation of approvals and changes.
