Can I change the order of PDFs before merging?

Yes. Reorder the list so chapters, exhibits, or cover pages appear in the sequence you need before combining.

Is there a limit on how many PDFs I can merge?

Practical limits come from browser memory and file size. Very large or numerous scans may need splitting into smaller batches.

Will bookmarks and forms survive the merge?

Basic page content is preserved. Advanced interactive features, some bookmarks, or DRM-protected files may not transfer perfectly.

Do I need to install software?

No. The merge PDF tool is free to use—no desktop Acrobat install required for simple combines.
