How to Merge PDF Files
Combine reports, receipts, forms, or supporting documents into one PDF.
Quick answer: Combining files is useful when a submission asks for one PDF containing several supporting documents.
1. Gather the source PDFs
Put the files you want to combine in an easy-to-review order. Rename confusing files before selecting them if necessary.
2. Select files in order
Use the Merge PDF tool and select the documents in the order you want them to appear.
3. Review the combined file
Check that each source document is present, the page order makes sense, and no page has been accidentally omitted.
Useful submission pattern
For an application packet, a sensible sequence might be cover page, form, resume, supporting documents, and attachments. The exact order should follow the receiving organization’s instructions.

Frequently asked questions
Should I keep the original PDF?
Yes. Keep the source until you have checked and successfully submitted or shared the final version.
Why should I review the output?
PDF processing can affect page order, image quality, orientation, or file size. A quick review catches mistakes before they matter.
What if a website still rejects the PDF?
Read the exact error message. The portal may have a stricter file-size, page-count, filename, or file-format requirement than you expected.
