Merge PDF: what the result contains

Combine multiple PDFs in your chosen order.

Mixed page sizes aren’t a merge error

Merging joins complete pages; it doesn’t reflow them into one shared page size. A portrait invoice, a landscape chart and an A4 report can all remain different inside the same PDF.

Mixed page sizes are allowed, so the finished file can legitimately contain portrait, landscape and differently sized pages.

combine invoices or receipts into one record

Combine invoices or receipts into one record. Join chapters, reports or handouts before sharing. Both jobs fit because they ask the tool to do exactly what its output is designed for, without adding an unrelated conversion.

Don’t ask Merge PDF to do a different job

If you need to rearrange individual pages before combining files, organise the pages first. If you need every page to share one paper size, resize them instead of expecting a merge to normalise the layout.
