Add a PDF Review System to Your SaaS Product with Minimal Code

Every SaaS founder hits this wall eventually.

A user uploads a PDF, and the next question is, “Can I add comments or mark things up?”

You think, “Surely someone’s solved this already.”

Spoiler: most tools are either bloated, need plugins, or break halfway through a team review.

We needed a clean, browser-based PDF review systemsomething light, powerful, and fast. After digging through half-baked GitHub projects and overpriced enterprise options, I landed on VeryPDF HTML5 PDF Annotation Source Code License.

Game changer.

How I Found It (and Why I Stuck with It)

I was building a niche SaaS product for compliance teams to review scanned contracts. We needed annotations. Likereal annotations: highlights, comments, markup, replies, the works.

I tried a few open-source libraries. Half of them didn’t support Office files, others struggled on mobile. Some choked on large PDFs or didn’t support layering between multiple users.

Then I stumbled on VeryPDF’s HTML5 PDF Annotation solution. At first glance, it checked all the boxesmulti-file support, no plugins, REST API integration.

I gave the online demo a shot, and I was sold within minutes:

The Features That Actually Mattered

Full browser support

This thing runs smooth on Chrome, Safari, Edgeeven IE if you’ve still got clients stuck there. It’s HTML5-based, so no weird dependencies. And it runs on Windows, macOS, Linux, iOS, Androideverywhere.

Markup tools that make sense

Forget clunky toolbars. Users get intuitive access to:

  • Highlights

  • Strikethroughs

  • Freehand drawing

  • Text comments, point notes, and area comments

Everything’s layered. You can see what other users added, reply to comments, or burn annotations into the final file. Total control.

Support for over 50+ file formats

Most SaaS platforms need to handle more than just PDFs. With VeryPDF, we could load:

  • Office docs (Word, Excel, PowerPoint)

  • CAD diagrams

  • Visio files

  • Scanned images (TIFF, PNG, JPG)

For us, that flexibility was non-negotiable. Compliance reviewers don’t just look at PDFsthey use everything.

Export, email, and share annotated PDFs

The fact that our users could annotate a document and export or email it without leaving the browser? Massive time saver. Zero bounce between apps.

Real-World Use Cases Where It Shines

  • Teachers or course creators marking up assignments
