Frequently asked questions
Can I annotate the merged PDF afterwards?+

Will the table of contents from each paper be preserved?+
Bookmarks from individual PDFs are preserved within their page range. A combined table of contents would need to be added manually.
Is there a page count limit?+
Free users can merge files up to 2 MB each. Pro removes this limit, supporting large, image-heavy academic PDFs.
