You’re trying to convert an HTML file into a PDF in Landscape mode, but the output is stuck in Portrait—even after explicitly setting the "orientation": "landscape" parameter.
Why This Happens
This issue typically occurs because the HTML contains <style> tags that override the default orientation settings used by the PDF rendering engine. These styles often come from Microsoft Outlook or similar HTML generators, which embed formatting inside <style> elements in the head and body of the HTML.
How to Fix It
To correct the page orientation issue, follow these steps:
Step 1: Clean the HTML
Remove the <style> elements that may be interfering with layout rendering. These are usually found in HTML files exported from tools like Microsoft Word, Outlook, or email editors.
HTML with <style> (causes error):
<html xmlns:v=3D"urn:schemas-microsoft-com:vml" xmlns:o=3D"urn:schemas-micr=
osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" =

Cleaned HTML (fixes the error):
Simply remove or skip the <style> section entirely so the orientation setting works correctly:

osoft-com:office:office" xmlns:w=3D"urn:schemas-microsoft-com:office:word" =

</head>
<body lang=3D"NL" link=3D"#0563C1" vlink=3D"#954F72">
Step 2: Use Profile Parameters to Automate the Cleanup
Instead of manually editing HTML, use PDF.co profile parameters to automatically remove conflicting styles:
"profiles": "{ \"removeHTMLHeadStyleTags\":\"true\", \"removeHTMLBodyStyleTags\":\"true\" }"
This tells PDF.co to strip out <style> tags from the HTML before rendering the PDF.
Zapier: Use “Profiles” field in the PDF.co module
Make: Set profile params in the action settings
Postman or Other Clients: Add the
profilesfield to your JSON request body
Helpful Tips
Always check for embedded styles when using HTML from email tools or Word processors.+
Landscape mode works reliably with clean HTML or by using the profile filters.
Test your HTML using simple editors like Notepad++ or CodePen to preview layout.
