    Hello @Linda274776202tig,

    Thanks for reaching out. Could you share more details, such as whether this issue occurs with all InDesign documents, and provide screenshots of the export settings used, so we can better assist you? Also, try the suggestions shared here (https://adobe.ly/4qMfGHF) and let us know if they help.

    Looking forward to hearing from you.

    Anubhav

    Hello, thank you for trying to help me.

    InDesign 2025,
    my file is 348,288 KB in size.
    Through File - Export - to PDF, my file is still 806 KB and easy to send
    via email.


    InDesign 2026
    This is the same file, which is 348,288 KB in size.
    Via File - Export - to PDF, my file is still 328,828 KB in size and
    cannot be sent by email.

    I have been working like this for years and have never had any problems,
    but as soon as I do the same operation in 2026, I have problems.



    Met vriendelijke groeten

    Linda Deruyter

      Are you sure you're using exactly the same PDF export settings in both versions of InDesign? If so, then can you post screenshots of the settings. I wonder if you can also share the InDesign file. In addition, what's your operating system version?
