PDF Merge Tips & Information

Build polished, well-structured merged PDFs with these practical tips.

Info

Order in = order out

The final PDF follows the exact file sequence you set — including page numbering and section flow.

Tip

Prefix file names for easy sorting

Rename files 01_intro.pdf, 02_body.pdf before uploading so large batches stay in the intended order.

Info

Different PDF versions can be merged

PDFs from version 1.3 through 2.0 can be combined; the output adopts the highest version present.

Tip

Standardise page orientation first

Mix of portrait and landscape pages creates a jarring reading experience — align orientations before merging.

Info

Merging does not re-compress images

Images from each source file are embedded as-is; run compression after merging to shrink the combined file.

Tip

Add a cover page as the first file

Drop a branded cover PDF at position 1 to give the merged document a professional, polished look.

Info

Bookmarks can be preserved

Most merge tools retain individual document bookmarks as sub-entries under each file's section heading.

Tip

Proof the merged result

Scroll through the combined file to check page order, bookmark accuracy and that no pages were dropped.
