No documented PDF conversion workflow is established by the accessible Screenshotlayer sources. Screenshotlayer documents a webpage screenshot API that returns image formats—PNG by default, JPEG, or GIF—not a PDF. You can use it to capture a webpage as an image, but choosing an image format does not make a PDF. Its current detailed documentation could not be verified, so newer PDF support cannot be ruled out. If you need an API that explicitly returns a PDF, ScreenshotNeo documents PDF capture.

What Screenshotlayer’s API can—and cannot—be confirmed to do

Screenshotlayer’s accessible official FAQ lists PNG, JPEG, and GIF as screenshot output formats; the archived API specification also describes image output, not PDF. Screenshotlayer FAQ Archived API specification

That evidence supports using Screenshotlayer for webpage screenshots, but not claiming it converts a webpage directly to PDF. The current detailed documentation link redirects to APILayer documentation that was not accessible for verification. Therefore, the precise conclusion is that PDF output is not established by the reviewed accessible documentation, rather than that Screenshotlayer definitely has no newer PDF feature. Screenshotlayer documentation

If a PDF is essential, verify the current API reference or get confirmation from Screenshotlayer before building against a PDF parameter or expecting a PDF response. Do not treat PNG, JPEG, or GIF output as a PDF substitute if your workflow requires searchable text, PDF page dimensions, or a PDF file.

Make a documented Screenshotlayer screenshot request

The archived specification gives the capture endpoint as http://api.screenshotlayer.com/api/capture. A request requires an access_key and a target url that includes its protocol. The vendor says the access key is available in the account dashboard. Archived API specification Screenshotlayer FAQ

The example below requests a PNG screenshot. It saves the response as an image, not as a PDF. The archived specification says paid customers may connect over HTTPS; verify current account terms and endpoint guidance before relying on HTTP or HTTPS behavior.

The FAQ also describes a free allowance of 100 snapshots per month, paid subscriptions starting at USD 19.99 per month, and overage charges after exceeding a plan’s request allowance. These are vendor-published terms on an undated FAQ page accessed in 2026; confirm current pricing and quotas with Screenshotlayer before budgeting. Screenshotlayer FAQ

If the result must be a PDF

Screenshotlayer’s accessible sources do not establish an API parameter or workflow for receiving a PDF. If you already have an image capture, you could convert that image to PDF with a separate tool, but that produces an image-based PDF and does not demonstrate that Screenshotlayer itself supports PDF capture. For a direct webpage-to-PDF API, use a service whose current documentation explicitly describes PDF output and the controls your workflow needs.

Troubleshooting a Screenshotlayer request

  • Missing or invalid access key: Check that the request includes access_key and that the value is copied from the account dashboard. The archived specification lists key errors; confirm the current error reference because its example and common-error table conflict on code 104.
  • Usage limit reached: The specification includes usage-limit errors, and the FAQ says overage charges may apply after plan allowances. Check account usage and current subscription terms rather than relying on an ambiguous archived numeric error code.
  • Invalid target URL: Include the full URL with https:// or http://, not just a domain name.
  • Unexpectedly stale image: The API documents caching with a default TTL of 2,592,000 seconds (30 days). Consider a lower TTL or force=1 for a fresh capture, subject to current API behavior.
  • Animation or effects are missing: The FAQ says delay can allow animations or effects more time to load. Adjust the delay for the page, while accounting for longer request time.
  • Image received when you expected a PDF: The accessible Screenshotlayer format list is PNG, JPEG, and GIF. An image response is not a PDF; verify current vendor documentation or choose an API with explicit PDF output.

FAQ

Can Screenshotlayer return a PDF directly?

The accessible FAQ and archived specification do not document PDF output. Since the current detailed documentation could not be verified, check Screenshotlayer’s current documentation or support before treating that as a definitive statement about newer features.

Which image formats does Screenshotlayer list?

Its FAQ lists PNG (default), JPEG, and GIF. Screenshotlayer FAQ

Can I get a full-page screenshot?
