Add multiple PDFs

Set the order
Move files up or down until cover pages, forms, certificates, and attachments are in the right sequence.
Merge and download
Create the combined PDF, open it once, and confirm the page order before submission.
Why browser-local merging matters
PDF packets can include ID documents, salary slips, invoices, statements, and signatures.
Local merging keeps the combine step on your device and reduces the need to send sensitive files to random upload sites.
Before submitting the merged file
Check page order, duplicate pages, file size, and whether all pages are readable.
If the final file is too large, compress it only after merging so you do not compress files multiple times.
