SelectPdf is an HTML-to-PDF solution for developers, centered on the Online HTML to PDF REST API and the SelectPdf for .NET Library. The online API can convert a web page URL or raw HTML into a PDF, with support for both synchronous calls and asynchronous job submission followed by result polling. Its v2 API can be used directly via HTTP GET/POST, or integrated through client examples for PHP, Python, .NET, Java, Node.js, Ruby, Perl, and more.
The feature set is fairly comprehensive: it supports HTML5/CSS3/JavaScript, with a choice of rendering engines including WebKit, Restricted, Blink, and Chromium, with Chromium recommended for new integrations. For PDF output, you can configure page size, orientation, margins, headers and footers, page numbers, document title/author/keywords, viewer layout, password protection, background color, and more. For web page loading, it supports wait times, timeouts, cookies, HTTP Basic Auth, CSS Print, disabling JavaScript, preserving links, and other options. Advanced features include generating bookmarks from CSS selectors, hiding elements, converting only specific elements, and extracting the coordinates of HTML elements in the resulting PDFβuseful for post-processing workflows such as e-signatures, form filling, and annotation overlays.
The online API offers a 7-day free trial key with 200 conversions included. There is also a keyless Demo endpoint, but it adds a watermark, is limited to 5 pages, and has rate limits. Paid monthly plans range from $19/month for 2,000 conversions to $449/month for unlimited conversions; annual plans range from $190/year to $4,490/year. The .NET Library is licensed perpetually, priced at $499-$1,599, and includes 1 year of maintenance and support.
Its strengths are fine-grained parameters, ample documentation and examples, a low barrier to integration across languages, and engineering-oriented features such as asynchronous jobs and coordinate extraction. The downsides are that the online API depends on an external service, and the documentation reviewed does not specify SLA, data retention, regional deployment, or security certifications. The Demo is only suitable for evaluation, with clear limitations. If you need a fully local deployment, you should carefully assess whether the .NET Library license fits your architecture requirements.
It is suitable for SaaS products, enterprise admin systems, invoices and contracts, reports, web archiving, and signature automation systems. The reviewed materials do not provide information on access from mainland China, so its availability is unknown; before production use, it is advisable to test API latency, stability, and payment availability. If network conditions or compliance requirements are restrictive, alternatives include self-hosted Puppeteer/Playwright, wkhtmltopdf, WeasyPrint, or similar services such as PDFShift and DocRaptor.
