What this conversion produces
Combine related PDF pages into a single document for sharing or archiving. Add at least two PDFs and use the file-list arrows to choose their order. Each source contributes all its pages in sequence. Page sizes and page content are copied, avoiding an unnecessary image conversion that would otherwise make selectable text harder to use.
Supported input and practical limits
This tool accepts up to eight unencrypted PDFs within a combined 4 MiB upload and a total of 200 pages. It copies pages rather than entire document-level structures, so bookmarks, signatures, attachments and interactive forms are not guaranteed to survive. Any modification invalidates existing digital signatures. The output is a new PDF; retain source documents when their original signatures or interactive behavior matter.
What should I know before converting?
This tool accepts up to eight unencrypted PDFs within a combined 4 MiB upload and a total of 200 pages.
Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
