Both render identical pixel output since both drive Chromium, but differ in operational overhead—PuppeteerSharp requires managing browser binaries, process pooling, memory budgets, and restart policies, while IronPDF runs the engine in-process with no separate browser lifecycle to manage. The piece frames the choice around infrastructure cost at scale (e.g., 10,000 reports a night across hundreds of tenants) rather than rendering fidelity, and is written by the IronPDF vendor team, who disclose their affiliation and position IronPDF as the more operationally simple option while acknowledging PuppeteerSharp's broader browser-automation utility. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I convert a Chart.js dashboard to PDF in .NET when the charts are rendered client-side with JavaScript? Use a real browser engine that executes the page's JavaScript and waits for the charts to finish painting before capturing the PDF, since a static HTML-to-PDF pass produces blank rectangles where canvases should be. In PuppeteerSharp, WaitForFunctionAsync polls until a custom readiness flag (like window.chartsReady) flips, then PdfDataAsync captures the document. IronPDF's WaitFor.JavaScript achieves the same result with an in-process Chromium engine and no browser process to manage. _daily.dev surfaces practical .NET PDF rendering approaches for developers building reporting pipelines._ ### What is the memory and infrastructure cost of running PuppeteerSharp in production versus IronPDF? PuppeteerSharp requires shipping a roughly 150 MB Chromium binary pinned via BrowserFetcher, budgeting 200-500 MB of RAM per browser instance, and managing pooling, recycling, and restart policies to prevent zombie processes and memory growth over long-running sessions. IronPDF embeds Chromium in-process, removing the fetcher step, instance pool, and separate process to monitor, trading some flexibility for a smaller operational surface. _Comparing infrastructure costs like this helps teams choosing a PDF rendering approach on daily.dev._ ### Why does --disable-dev-shm-usage matter when running PuppeteerSharp in Docker? Docker provisions only 64 MB of /dev/shm shared memory by default, which is too small for Chromium's needs, so the --disable-dev-shm-usage flag keeps Chromium from relying on that limited shared memory space and avoids crashes during headless rendering inside containers. _Developers containerizing browser-based .NET services track flags like this via daily.dev._ ## Similar posts on daily.dev - [How to Convert HTML to PDF in C\# \(.NET 10 Guide\)](https://daily.dev/posts/how-to-convert-html-to-pdf-in-c-net-10-guide--zhyfillpr) · Code with Mukesh · 20 upvotes · 2 comments - [PDF Rendering Engines Compared: Choosing the Right One for Your App](https://daily.dev/posts/pdf-rendering-engines-compared-choosing-the-right-one-for-your-app-6uy9xdshw) · Syncfusion · 0 upvotes · 0 comments - [How to Export PDF Reports from Grafana OSS in 2026](https://daily.dev/posts/how-to-export-pdf-reports-from-grafana-oss-in-2026-mtpwdfa5n) · Skedler · 2 upvotes · 0 comments - [Generating Charts in Pure Ruby Without JavaScript](https://daily.dev/posts/generating-charts-in-pure-ruby-without-javascript-yqenrulz1) · RUBYLAND · 0 upvotes · 0 comments - [Write PDFs in React.
