PDF Viewing Diagnostic

A free test page for browser PDF support on front-desk workstations. Verifies your browser can render PDFs inline, that a sample renders without downloading, and that form fields and print work. Run it on the workstation where users are reporting trouble opening PDFs.

Read the Pdf Test guide for help reading the verdict or fixing each failure mode.

Privacy: All checks run locally in this browser tab. The sample PDF is served from this same site, and nothing about your browser, form input, or print attempt is transmitted anywhere. View source to verify.

Configuration

Driver: Browser PDF support

Takes about 30 seconds. You will be asked to confirm what you see on screen because no JavaScript signal alone can tell whether the PDF actually rendered. No data leaves your machine.

Form field check

Scroll the PDF above to the "Type your name" field. Click into it and type a few characters. Did the characters appear in the field?

Print check

Print the sample PDF above. Click the button below to try printing it directly. If nothing happens (most browsers block that), use the PDF viewer's own print control: hover the PDF to show its toolbar and click the print icon, or click into the PDF and press Ctrl+P (Cmd+P on a Mac). The print preview should show the PDF (the "desktest.net PDF render test" document), not this page. Did a print dialog for the PDF open?
