Common Use Cases
Combine document sets
Merge supported PDF files such as reports, forms, contracts, or scanned pages into one easier-to-share document.
Prepare submission packets
Combine PDF files for applications, client packets, school materials, or project deliverables when one file is easier to upload.
Keep related pages together
Merge separate PDFs when they belong in the same archive, handout, or reference document.
Tips & Best Practices
Check the file order
The merged result follows the order shown in the upload list, so confirm the sequence before starting.
