Microsoft 365 rest api to convert pptx/vsdx to png

Question

Hello,

On my linux server, I would like to use microsoft 365 rest api to convert pptx/vsdx to png. Is it possible? I found onedrive rest API [https://learn.microsoft.com/en-us/onedrive/developer/rest-api/api/driveitem_get_content_format?view=odsp-graph-online] that can convert some formats to jpg. I would appreciate any documentation about it.

Best regards,

Hi @PACHECO LLANOS, Aracely ,

Yes, correct. You can use Download/convert an OneDrive file in another format Microsoft Graph Rest API and currently there is no Microsoft Graph API avialble to convert .vsdx format into other file format.

Here are the few examples to convert an OneDrive .pptx file to .jpg format using Microsoft Graph API.

https://graph.microsoft.com/v1.0/me/drive/root:/{filename.pptx}:/content?format=jpg&width={width-value}&height={height-value}  
https://graph.microsoft.com/v1.0/users/{user-id} or {UserPrincipalName}/drive/root:/{filename.pptx}:/content?format=jpg&width={width-value}&height={height-value}  

Note: As per my testing in Postman API tool, only first slide of PPTX file is being converted into .jpg format and where as if we convert .PPTX file into .PDF format then all the slides included in the conversion.

**Example **:

https://graph.microsoft.com/v1.0/me/drive/root:/TestPPT.pptx:/content?format=jpg&width=800&height=800  

**Example **:

https://graph.microsoft.com/v1.0/users/******@o365XXX.onmicrosoft.com/drive/root:/TestPPT.pptx:/content?format=jpg&width=800&height=800  

Here is the API to convert an OneDrive .pptx file to .pdf format.

https://graph.microsoft.com/v1.0/me/drive/root:/{filename.pptx}:/content?format=pdf  
https://graph.microsoft.com/v1.0/users/{user-id} or {UserPrincipalName}/drive/root:/{filename.pptx}:/content?format=pdf  

Examples:

https://graph.microsoft.com/v1.0/me/drive/root:/TestPPT.pptx:/content?format=pdf
https://graph.microsoft.com/v1.0/users/******@o365XXX.onmicrosoft.com/drive/root:/TestPPT.pptx:/content?format=pdf

Hope this helps.
