One file beats five

Application packets, reports with appendices, month-end bundles — recipients want one file. A merged PDF can't lose an attachment and always presents pages in order.

Merging preserves quality: pages are copied verbatim, not re-rendered.

02

Getting the order right

Upload the files, then arrange them in the list — cover document first, attachments after. The merged PDF follows the list exactly.

If the order comes out wrong, don't re-merge: Organize Pages lets you click the pages into the right sequence afterwards.

03

After the merge

Long merged documents benefit from Add Page Numbers — one continuous numbering beats three internal 'page 1's.

Too big to send? Compress PDF is the next stop. The whole chain stays inside PixPDF.
