When it helps to merge PDF files
Many websites and offices ask for one file, not five. Merging saves you from attaching documents one by one and hoping they arrive in the right order.
- Job applications: put your resume, cover letter and certificates into a single PDF for a portal that accepts only one upload.
- Bookkeeping: collect a month of invoices or receipts into one file for your accountant.
- Travel: keep tickets, hotel bookings and insurance papers together, so everything opens from one place on your phone.
- School and university: join scanned handwritten pages with a typed title page before handing in an assignment.
Tips for a clean merged PDF
Name your files with numbers first, like 01 cover.pdf and 02 resume.pdf. They will then appear in a sensible order, and you only need small changes before merging.
Check each file before you combine them. Remove blank scanner pages with Delete PDF Pages and fix sideways scans with Rotate PDF. It is easier to fix one small file than to hunt for page 37 in a big one.
Merging adds the sizes of all files together. If the final document is too large for an email or an upload form, run it through Compress PDF afterwards.
What merging does and does not change
Merging only joins documents. It does not resize pages, change fonts or touch image quality. A landscape spreadsheet page stays landscape, and a small receipt stays receipt sized next to full A4 pages.
Your original files are not changed either. FileKiwi creates a new PDF and leaves the source files exactly where they were.
Have photos instead of PDFs? Turn them into a PDF first with the image tools, then add that file to your merge. The order you set on the cards is the order readers will see.
