Annotations and collaboration
Teams need to highlight, comment, and collaborate inside documents.
Without it, workflows break outside your product.
Production-grade PDF, built into your product.
Viewing is the easy part. CloudPDF adds annotations and collaboration, permissions, signed URLs, and scale that production demands — as a drop-in viewer or headless components, hosted or self-hosted.

The problem
A viewer is just the beginning.
The moment PDFs hit production, basic viewing isn't enough. Teams run into the same roadblocks that slow down launches and add complexity.
Permissions and signed URLs
Secure access, expirations, and role-based controls are table stakes.
Ad-hoc sharing and downloads create risk and support load.
Custom UI complexity
Building a polished PDF experience with permissions and tools takes months.
Reinventing the viewer slows down your roadmap.
Hosting, scale, and compliance
Global delivery, large files, compliance, and audit logs are hard to get right.
Infrastructure distractions pull focus from your product.
CloudPDF gives you the workflow layer, not just the viewer.
The hard partYou could build
You could build
it yourself.
The demo is easy. The production reality is not.
Start with pdf.js, wire up a viewer, and ship the first demo fast. Then the hard part begins: annotations and collaboration, permissions, signed URLs, audit logs, compliance, huge files, global scale, and self-hosting.
The first 20% is a weekend.
The last 80% is where roadmaps go to die.
We know — we've handled every one of these edge cases inside CloudPDF.

The plan
CloudPDF handles the hard parts.
Three steps to production — whether you want it live in ten minutes or wired deep into your own stack.
1
Choose how it runs
Start on managed SaaS, or deploy the server into your own environment.
2
Drop in the viewer
Upload a document, then use the ready-made viewer or go headless with components and APIs.
Ready-made Viewer
Headless & APIs
const instance = await CloudPDF.create({ document: "contract.pdf", features: ["annotate", "sign"] }); instance.load();
3
Turn on the hard parts
Annotations, permissions, signing, and collaboration — without custom infrastructure.
