Product
PDF
Device & OS

Scenario
Embedding an interactive PDF on a web page for users to complete and submit via email or a server.
Observed behavior
Standard embedding displays the PDF, but interactive form filling and email submission heavily depend on the specific browser capabilities, native PDF viewers, and the local email client configurations of the visitors.
Before you start

Ensure your form fields and submission buttons are fully configured and tested in a standard desktop PDF application, as browser-based PDF viewers often have limited support for interactive elements.

Embed Using an Iframe or Native HTML Tags

Use standard HTML tags to display the fillable PDF directly on your website page, allowing users with compatible browsers to interact with it.

While embedding is straightforward using HTML, remember that built-in web browser viewers (like Chrome or Safari's default PDF readers) might not perfectly support fillable fields or 'mailto:' submission buttons. Always provide a fallback download link for the best user experience.

1
Upload the PDF to your server

Upload your configured fillable PDF file to your website's hosting server or a secure document hosting service to obtain a direct URL.

2
Insert the iframe code

In your website's HTML editor, add an iframe tag pointing to the file: <iframe src="your-form.pdf" width="100%" height="600px"></iframe>.

3
Add a fallback download option

Right below the embedded PDF, add a direct hyperlink to the file instructing users to download it if they encounter issues submitting the form within their browser.

Submission Limitations: If your PDF relies on a 'mailto:' submit button, it will only work if the visitor has a default desktop email client (like Outlook or Apple Mail) configured on their device.

Frequently Asked Questions

Why does my embedded PDF form not submit when users click the button?

Most modern web browsers use lightweight built-in PDF viewers that prioritize reading over interactivity. These viewers often lack the ability to execute the scripts required for form submission or cannot trigger the device's local email client, causing the submit button to fail.

How does an email submission button work inside a PDF?

An email submission button in a PDF uses a 'mailto:' action. When a user clicks it, the PDF application tries to open the default desktop email client (such as Microsoft Outlook) to attach the form data and send it. If the user relies solely on webmail (like Gmail in the browser) or hasn't set up a default mail app, the action will not complete.

Can I force visitors to download the fillable PDF instead of viewing it in the browser?

Yes. Instead of using an iframe to embed the document, you can provide a direct link to the file using the HTML anchor tag with a download attribute: <a href="your-form.pdf" download>Download Form</a>. This prompts the user's browser to save the file locally, encouraging them to open it in a dedicated PDF application.

Can visitors use WPS Office to fill out my website's PDF form?

Absolutely. Once visitors download the interactive PDF from your website, they can open it in WPS PDF. The software fully supports interactive fields, allowing users to type in their information, save the filled form, and use built-in features to share or submit it securely.
