Loss of Image in Header : DOCX to PDF using Sharepoint Graph API

Question

Hi Team,

I'm trying to convert docx file to pdf using SharePoint Graph API by calling this following GET request -

https://graph.microsoft.com/v1.0/sites/894f9bf8-01d7-471e-82ac-7354e4c21200/drive/root:/File_Conversion_Test/Header_Banner_Loss_Document.docx:/content?format=pdf

In the converted PDF file, there is a loss of Image which was present in the header.

I tried using OneDrive Connector in Power Automate as well to convert the docx to pdf but it has the same issue - Loss of Image in Header.

Is there any limitations on any kind of images in the docx file that are not convertible to PDF in SharePoint API.

Original DOCX file has following header -

When converted to PDF using SharePoint graph api, image no longer exists -

I can share the docx file as well if required.

Hi @Mani Wadhwa ,
Per my test, I can convert the docx file with a header to pdf successfully.

After doing some research, there are following reasons might cause images disappear after converting the document to docx or PDF:

1. Image size: If the inserted image size is larger than 10 MB, then it will not get printed during PDF export.
2. Authenticated images: Images inserted directly from other sources into a document may require some additional authentication to access and process the image during PDF conversion. Such images will not be shown while converting the document to PDF. To insert authenticated images, you can download these images locally into a folder in your computer, and then insert the same in your Writer document.
3. If a document contains base64 or WMF images, then such images will not get exported [due to limitations] while converting the document to docx, rtf or pdf. To avoid this issue, please use image formats like JPEG , JPG or PNG to yield better results.
4. Floating images will not be shown while converting the document into PDF, since the image is too wide to fit the page size. To avoid this issue, try resizing the image dimensions and try again.
