I’m having this same issue. I’m trying to export a resume file that should be very small. It’s a single page with no imagery and it's exporting at 74 kb. The same file exported with inddd 2025 exported at more than half the file size. Now I can’t apply to jobs because the file size is too big to upload! grrrr.

74 kb is quite small. What really is the problem?

Unchecking the box for editable file makes no difference. I have a brochure currently sitting at 724mb with no embedded images. Unchecked the box and it's still over 700mb. What is going on adobe !

And what’s the PDF size of this brochure when exported from InDesign 2025?

Hello everyone,

I believe the problem is the last page of the PDF. If you edit the PDF and delete the last page, the file size will be greatly reduced.

I have an InDesign file with several images. The last artboard is identical to the first (design, text, etc.) and the size difference between them is enormous.

Hello everyone,

Please try the suggestions shared by our experts:

Uncheck the option “Preserve InDesign editing capabilities.”
Avoid embedding any images in your InDesign document.

Let us know if this resolves the issue.

Can you please elaborate - do you mean that you don’t see this option in your PDF export dialog?

Also having this issue with both my preset and the default "smallest file size". PDFs of the exact same file exported on 2025 were 5-7MB and are now 48-50MB ex[orting with 2026 Indesign.... not ideal going to have to remove 2026 and redownload 2025 if possible to meet deadlines.....

Hi,

Quick fix that I discovered but not a solution is you have to unceck : "Perserve Indesign editing capabilities" then the files are the normal size.

That is actually the solution. By maintaining InDesign edition capabilities, you are adding a tremendous amount of data to the file.

You also can't copy and paste from 2025 to 2026 without it making it in to some sort of eps? WHY?

Sorry, that's either way (2025-2026 & 2026-2025)

Hi James,

Your comment appears to be a different matter relative to this post. May I suggest you start a new post and describe your challenge with more detail?

I’m experiencing the same issue and have reverted back to the 2025 version until it’s resolved. It’s impossible to run a professional business on software that isn’t consistent. This problem seems to be happening more frequently, likely because the Adobe suite is being updated almost daily. I miss the days when we had properly tested disc or download releases that were updated annually, rather than rushed updates pushed out for the smallest changes.
