Merge PDF files

Add PDF files, arrange the source-file order, then create one document containing their pages in that order.

Processing and privacy

Merging runs in browser memory. Source PDF bytes are not sent to a Stocknivo conversion API. The application must load before use, so this is not a promise of offline operation.

How merging works

Select 2 to 20 PDF files and move whole files earlier or later in the list. All pages from each file are copied in their original page order; this tool does not preview or reorder individual pages.

Limits and document details

Each source PDF may be up to 50 MiB and the selected files may total 200 MiB. The merged document is limited to 1,000 pages. Password-protected or malformed PDFs may fail. Forms, annotations, bookmarks, attachments, metadata, and signatures are not guaranteed to be preserved.
