Frequently asked questions

Can I convert either HTML or a webpage URL to PDF?

Yes. Set type to html and put your HTML in content, or set type to url and provide a public HTTP or HTTPS webpage URL. The output is a downloadable PDF.

How do I create a landscape PDF?

Set landscape to 1 for landscape orientation, or 0 for portrait. Test a representative page to confirm that the content fits the chosen orientation before using it in an automated export.

What are the documented input size limits?

Raw HTML can be up to 5 MiB. A webpage URL can be up to 2,048 characters and must use public HTTP or HTTPS. Check the input type before applying the corresponding limit.

Does the API return PDF bytes or a download link?

The documented success result includes pdfPath, an HTTPS URL for the generated file. Download the PDF into your own storage if you need to retain or distribute a copy.

Will a PDF look exactly like the interactive webpage?

Do not assume an exact match. A PDF is a fixed-page output, while a webpage can depend on responsive layout, fonts, and interactive content. Test your own HTML and styles with the Demo before relying on the layout.

What does the 5 requests per second limit mean?

It is a request-rate limit, not a concurrency allowance. Keep your request rate at or below 5 per second. If the service returns a rate-limit response, reduce the frequency and retry with backoff.

Is total paid usage limited?

There is no total request cap during an active paid subscription and no usage-based overage charge.

How does the free trial work?

Each account can receive a limited trial key. Requests are shared across APIs in the same category. Check Trial Keys for the exact allowance and remaining requests.

How do renewal and cancellation work?

The plan renews annually until canceled. Manage or cancel the renewal from Dashboard → Orders & Billing. Access continues through the paid period after cancellation. See the Terms of Service for the current refund policy. If the billing portal is unavailable, contact support.
