About SelectPdf
from our crawl and measurement
SelectPdf describes itself simply: "Convert HTML or any URL to PDF, a perpetual.NET library or a REST API. 22M+ NuGet downloads, shipping since 2014. Free trial, no credit card." To AI engines like ChatGPT and Perplexity it is partially visible, scoring 6.6 out of 10, readable in places and missing in others.
On the page itself the strengths are clear: structured data describing the business, a clear heading structure, a clearly stated business identity, visible credibility markers, crawler access and the files AI engines look for and sitemaps and entity links AI can follow.
Away from its own site, other sites link to it. There is some, but not much, sign that the domain is only lightly established. Beyond that, AI engines do not yet recognise it as a distinct business, there is no press coverage to draw on, nobody is discussing it where AI engines look and it does not come up on Reddit. Those are earned elsewhere on the web, not fixed on the site itself.
The site links to no social profiles, so there is nothing tying the brand to a wider presence.

What this score means
Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 6.6/10, SelectPdf has a working base to build on - fixable, and the signals above are where to start.
Frequently Asked Questions
What is SelectPdf?
SelectPdf is an HTML-to-PDF toolkit for developers, available as a perpetual self-hosted .NET library (runs in-process inside your app) and as a cloud REST API you call from any language. It has shipped since 2014 with 22M+ NuGet downloads.
Is SelectPdf free?
Yes. The .NET library has a free, no-limit trial (every page watermarked) and a separate free Community Edition capped at five pages; the Online API has a free trial plus a keyless watermarked demo. Paid options are a perpetual library license from $499 or metered API plans from $19–$449/month.
Which .NET versions does the library support?
The SelectPdf .NET library supports .NET Framework 2.0+/4.0+, .NET Core and .NET 5–10, including ASP.NET and ASP.NET MVC.
Does SelectPdf work on Linux or non-.NET stacks?
The .NET library runs on Windows. For Linux, macOS or any non-.NET language, use the SelectPdf Online API — the same engine over REST, callable from cURL, JavaScript, Python, PHP and Ruby.
Should I use the .NET Library or the Online API?
Use the .NET library for in-process conversion with no network call, perpetual per-developer licensing, or on-prem and compliance control. Use the Online API for polyglot stacks, a quick start with no install, or spiky load. Both use the same engine and produce identical output.
What rendering engine does SelectPdf use?
SelectPdf renders with a modern headless Chromium engine by default; Blink and WebKit engines are also available. Current HTML, CSS and JavaScript convert the same way they display in a browser.
How do I convert HTML to PDF in C#?
Install the Select.HtmlToPdf NuGet package, create an HtmlToPdf converter, call ConvertUrl or ConvertHtmlString, then save the PdfDocument — about three lines of C#. The same conversion is one REST call with the Online API.
Which rendering engines run on which .NET frameworks?
SelectPdf ships four rendering engines — WebKit, WebKit Restricted, Blink and Chromium. WebKit, WebKit Restricted and Chromium run on every supported framework from .NET Framework 2.0 onward, while the Blink engine requires .NET Framework 4.6.1 or later (.NET Core and .NET 5–10).
