Merging PDFs looks simple, but a good result depends on more than placing several files into one document. Before combining files, check that every document belongs in the final package and that the pages are already readable in the correct orientation.
Open each PDF first. Confirm that it is not password protected, corrupted or missing pages. Rename files clearly if you are working with several versions. Names such as “invoice-final.pdf” and “invoice-final-v2.pdf” make mistakes more likely, so use dates or descriptive names where possible.
Think about how the recipient will read the finished document. A cover letter normally belongs before supporting documents, while appendices and receipts usually belong at the end. If the PDFs contain their own page numbers, remember that those printed numbers will not automatically change simply because the files are merged.
After merging, open the new file from beginning to end. Check the first page, last page and the transition between every source document. Look for unexpected blank pages, rotated pages, duplicate content and unusually large file size.
If you need to combine files now, you can use the My PDF Kit Merge PDF tool.
Give the final file a meaningful name, confirm that it opens on another device if possible, and verify that no draft notes or personal information were included accidentally. For business or legal documents, keep an untouched copy of the original source files as well.
