How to Display a PDF Inline in an Email Instead of as an Attachment
Question details
The user wants to display a completed PDF form directly within the body of an email rather than sending it as a file attachment.
- Product
- PDF / Email Client
- Device & OS
- not provided
- Scenario
- Sending a completed PDF form via email using Acrobat JavaScript and mailDoc.
- Observed behavior
- The PDF is sent as an attachment, but the recipient prefers to see the content immediately inside the email message body.
Understand that email clients like Outlook control how attachments are rendered. To force inline display, you will need to convert the PDF content into a supported inline format, such as an image or HTML.
Convert the PDF to an Image for Inline Email Display
Since email clients cannot natively render PDF files inline, converting the PDF to an image (JPG/PNG) allows you to paste it directly into the email body.
Email applications like Outlook restrict PDFs to attachments for security and formatting reasons. By exporting your PDF as an image, you bypass this limitation and ensure the recipient sees the content immediately upon opening the email.
Open your PDF in a PDF editor and use the 'Export to Image' or 'Convert to Picture' feature to save the document as a JPG or PNG file.
Open your email client (e.g., Outlook), create a new message, and click 'Insert' > 'Pictures' to place the image directly into the email body.
Convert PDF Content to HTML
If you need text to remain selectable, converting the PDF to HTML allows you to paste the formatted text directly into the email.

Frequently Asked Questions
Why does Outlook always show my PDF as an attachment?
Outlook and most other modern email clients do not have built-in PDF rendering engines for the email body. They treat PDFs as distinct file types that must be opened in a dedicated PDF viewer for security and layout preservation.
Can Acrobat JavaScript force an email client to open a PDF inline?
No. While Acrobat JavaScript (like the mailDoc function) can automate the creation of an email and attach the PDF, it has no control over how the receiving email client chooses to display that attachment.
Is there a way to send an interactive PDF form inline?
Unfortunately, no. Interactive elements like fillable fields, dropdowns, and buttons require a dedicated PDF reader to function. If you place the content inline as an image or HTML, all PDF interactivity is lost.
How can I share a PDF so the recipient sees it immediately?
Besides converting it to an image, you can upload the PDF to a cloud drive (like WPS Cloud or Google Drive) and paste the sharing link in the email, or use an email marketing tool that embeds PDF previews.
