    This happens with any bitmap image regardless of the file format.

    I used the Default PDF Preset with "Standard:None", and Compatibility: Acrobat 7(PDF1,6)" in both versions of Illustrator. I have tried all the different Standards (PDF/X-***) and the file size only changes slightly due to the Compression settings changing.

    The Compression is Zip and set to not downsample.

    XMP asset manifest in both PDFs identifies only one source bitmap, using the same Photoshop document ID and instance ID. So Illustrator 2026 still knows that all nine placements originated from the same embedded image. It simply doesn't reuse that image when constructing the PDF.

    I tired to upload the files here but either something is wrong with the uploader or the file size that can be uploaded is tiny.

    I put some smaller test files that I have been using in here:
