I create newsletters for a local car club and on October 31st, i exported it to a Adobe PDF (Interactive) file and the result was a 1.5 MB file. today, I attempted the same export but the output is now 131.9 MB and the only change i noticed was Indesign was updated to 2026 version. 

The newsletter is 7 pages, but it doesn't matter if i attempt to export all 7 or just 1, the output is always 131.9 MB. If I select  to create seperate PDF files, each of the files is about 200KB (which is probably normal) but i need them as a single file in order to upload them to the website. 

How can i get this resolved?

TIA

    PDF Export has not changed. Either you have different settings or different content.

    I restored Indesign 2025 and the Export function works as normal and creates a 1.5MB file rather than the 301MB file as Indesign 2026 does. Unless the upgrade changes a default setting that would cause this, there is something in the 2026 update.

      I am also having this same issue.  I am creating files with a bleed FOR PRINT.  I am not converting to RGB, as these are CMYK, at a high res for large format printing.  This exact file in 2025 was around 18MB.  I've updated with small changes to the text, with the same EXACT settings and no changes to the images; the file is now 543MB.  This is insanity; what can we do to fix this?

        *while exporting to "High Quality Print" PDFs. ("Press Quality" is still obnoxiously large that my print vendors reject the PDF.)

        I too am having the exact same problem. All the files I export in Ver 2026 are too big compared to the last Indesign version 😞

          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.

          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?
