Generate PDF & Images from HTML in ASP.NET Core using Rotativa + wkhtmltopdf | No Server Install

Learn how to generate PDF and Image reports from HTML in ASP.NET Core using Rotativa.AspNetCore and wkhtmltopdf — the same engine used by enterprise systems worldwide.

In this complete tutorial, I show you how to:

Convert Razor Views (HTML) into PDF and PNG

Bundle wkhtmltopdf.exe inside your ASP.NET Core app

Avoid installing anything on the server

Make your PDF engine production-safe

Handle high traffic using SemaphoreSlim

This approach is ideal for:

Invoices

Reports

Certificates

Bills

Dashboards

Downloadable documents

and it works on shared hosting, IIS, Azure, and cloud servers.

🔽 Required Downloads

wkhtmltopdf (PDF & Image Engine)
👉 https://wkhtmltopdf.org/downloads.html

Microsoft Visual C++ Runtime (needed for wkhtmltopdf)
👉 https://aka.ms/vs/17/release/vc_redist.x64.exe
Install-Package Rotativa.AspNetCore

🧠 Why this method is powerful

Instead of using RDLC or Crystal Reports, this system uses:

Razor View → HTML → wkhtmltopdf → PDF / Image
This means:

You design reports using HTML + CSS

Pixel-perfect layout

No report designer needed

Works on all platforms

This is how modern enterprise reporting is done in ASP.NET Core.
