Merge, then compress
Merging is additive: five 2 MB reports become one 10 MB document. If your email gateway caps attachments at 10 MB, run the merged file through the compressor afterwards to bring the images down without touching the text.

Frequently Asked Questions
What does PDF merge mean?+
A PDF merge concatenates several documents into one file while keeping every page's original layout, fonts and images intact.
Is merging the same as combining?+
Yes — merge, combine and join all describe the same operation on PDF documents.
Does a merge compress the file?+
No. The merged size is roughly the sum of the inputs. Use our Compress PDF tool afterwards if you need a smaller file.
Can I merge and then split again?+
Yes. Nothing is lost in a merge, so the Split PDF tool can pull any page range back out later.
