WHAT YOU GET
A real trial, not a demo.
  • 200 conversions across 7 days — enough to integrate and stress-test against real inputs.
  • All four engines — WebKit, Restricted, Blink and Chromium (CEF). Pick the one that renders your pages best.
  • Every endpoint — HTML to PDF, URL to PDF, PDF merge, PDF to text, web elements, async jobs.
  • Full parameter surface — same 90+ conversion options the paid plans expose.
  • No watermark on the API output. The watermark only appears on the keyless online demo.
  • Any language — official SDKs for .NET, Java, Node.js, PHP, Python, Ruby and Perl, plus a plain REST endpoint for everything else.
No credit card, no auto-conversion to paid. When the trial ends, conversions simply stop — pick a plan on /api-pricing/ only if you want to continue.
§WHAT YOU CAN DO

The trial unlocks every endpoint.

No "trial-only" stub endpoints, no quiet feature gates. The same surface that powers the paid plans is in front of you for 7 days.

HTML → PDF

Convert raw HTML

POST an HTML string with CSS and JS. Page setup, headers, footers, viewer preferences — all 90+ parameters available.

URL → PDF

Convert a public URL

Hand us a URL, we render and return the PDF. Cookies, custom headers and HTTP Basic auth all supported.

PDF MERGE

Combine PDFs

Multipart upload or remote URLs, with per-file passwords. Single endpoint, deterministic output order.

PDF → TEXT

Extract or search

Text or HTML extraction with page ranges. Case-sensitive / whole-word search returns per-match rectangles.

WEB ELEMENTS

Per-element coordinates

Pass CSS selectors and get back PDF rectangles per matched element — useful for form-fill automation downstream.

ASYNC

Long-running jobs

Submit with async=True, poll /api2/asyncjob/ until the PDF or web-elements payload is ready.

§READY FOR PRODUCTION?

Two paid paths, your call.

The trial validates the engine against your real inputs. When you are ready to ship, pick the hosted API or the self-hosted .NET library — same engine, different operations model.

HOSTED API
$19–$449/month

The same endpoints you just tested, on our fleet. From $19/month entry to $449/month dedicated. Pay only when conversions stay inside your plan; pricing on /api-pricing/.

SELF-HOSTED .NET LIBRARY
$499 perpetual

Run the engine on your own servers — no API calls, no per-conversion cap. Perpetual licence at $499, includes 1 year of updates. Download the watermarked trial first at /downloads/.

?FAQ

The trial, answered.

Seven quick answers about the 7-day API trial, the .NET library trial, how to upgrade, and what changes once you do.

No. The trial is fully free for 7 days and 200 conversions. No card on file, no auto-renew. When the trial ends, conversions stop and the key returns a quota-exceeded error — nothing is charged.
Everything the paid plans do. All four rendering engines (WebKit, Restricted, Blink and Chromium-CEF), every endpoint (HTML to PDF, PDF merge, PDF to text, web elements, async), and the full 90+ parameter surface. The API output is not watermarked.
Conversions stop at the 200-conversion cap or after 7 days, whichever comes first. To continue, pick a paid plan on /api-pricing/; the same key keeps working. Plans start at $19/month and scale to $449/month dedicated.
Any language that can speak HTTP — the SelectPdf API is a plain REST endpoint. We ship official SDKs for .NET, Java, Node.js, PHP, Python, Ruby and Perl, all wired up on the API documentation page. Anything else — Go, Rust, Elixir, raw curl — hits the same endpoint with the same parameters.
Yes. The SelectPdf .NET library trial does not need an API key — download it from /downloads/ and run it on-premise. The library trial stamps a watermark on each page so you can evaluate it; the licensed library produces watermark-free PDFs.

API subscriptions are billed by Stripe, our merchant of record.
