Combining existing PDF pages
Merge PDF files online to combine a cover, report, and appendix into one attachment. The service appends source page objects with pikepdf into a new PDF. Merging does not run the image compressor or deliberately turn pages into screenshots.
- Step 1
Use the workspace
Select the PDFs in the order you need them, choose Merge PDFs, then verify each document boundary in the output.
Output behavior and limits
Document-level bookmarks, forms, metadata, and signatures require verification. A merged file may remain large and may include mixed page sizes.
A two-page cover plus a five-page report should give seven pages. Confirm source order and the pages at each document boundary in the downloaded file.
Before replacing your original
