What it does
SelectPdf renders HTML and URLs into PDF through an online converter, REST API, and .NET libraries. Its toolkit also includes PDF text extraction, merging, and Word conversion.
Configure page size and margins, convert a URL or HTML string, then save and close the PDF in .NET, or retrieve it through REST. Free Community is a separate library package: commercial use is allowed without watermarks, but output is capped at five pages and advanced existing-PDF operations are excluded. The commercial library trial watermarks every page. The Online API trial instead gives 200 watermark-free conversions over seven days. Keyless browser converter and demo pages disagree about page limits and marks, so check the specific route.
Strengths
- Offers online and embedded conversion with detailed page controls.
Watch out for
- Community has a five-page cap and fewer advanced features; keyless converter/demo limits are inconsistently described.
