Appending one PDF to another
Insert PDF adds the pages of a second document to the end of a first one. It is a quick way to attach an appendix, add signed terms to a proposal, or append a new month's statement to an existing record without managing a list of files.
How it differs from Merge PDF
Insert PDF always works with exactly two files: a base document and the document to append. Merge PDF handles any number of files and lets you drag them into a custom order. Use Insert PDF for the simple case and Merge PDF when you are assembling several documents.
Quality and formatting
Pages from both files are copied as they are. Fonts, images, page sizes and orientation are preserved, so a landscape appendix stays landscape after a portrait report. Text in both parts remains selectable and searchable.
Password-protected files must be unlocked first, because their contents cannot be read without the password.
Placing pages in the middle
This tool appends at the end. To place the second document in the middle, append it and then move its pages with Reorder Pages, or split the base document and merge the parts in the order you need.
Tips
- Upload the main document first — it stays at the beginning.
- Rotate sideways pages in either file before combining.
- Compress the result if it is too large to email.
