What happens to a file that is larger than 3 MB

Posted on by

I want to use an existing SharePoint Online site with files as a content source, my questions are:


  1. When a file is over 3MB, is it simply ignored or only the first 3 MB of content accessed?
  2. Also, is there any plan to increase this 3MB limit to use any file stored in SharePoint Online? 


From Microsoft: Due to memory limits, generative answers can only use SharePoint files that are under 3 MB. If a file is larger than 3 MB, consider splitting it into multiple smaller files.

    Hi @AntG_NZ ,


    There is currently no documentation on how to handle files over 3MB. Unfortunately, there is no direct workaround to exceed this limit. However, you can consider the following approaches:

    1. Split Larger Documents: If you have files larger than 3MB, break them down into smaller chunks. Divide the content into separate files and process them individually.

    2. Leverage File Compression:

      • MS Word: Instead of embedding the entire file, insert a field that represents the file. MS Word also performs some file compression.
      • PDFs: Use PDF compression tools (e.g., Adobe Acrobat Pro) to reduce file size.




    Best regards,
