How to merge PDFs
- Choose two or more PDF files, or drag them onto the box.
- Use the ↑ and ↓ buttons to set the order. The first file in the list becomes the first pages of the new PDF.
- Select Merge PDFs and download merged.pdf.
What happens to your files
The merge runs in this browser tab using the open-source pdf-lib library, which is stored on FileKivo itself. Your PDFs are read into memory on your device, the pages are copied into a new document, and the result is offered as a download. Nothing is sent to a server, so the tool also works for payslips, bank statements and identity documents you would rather not upload to a stranger's website.
Pages are copied, not re-drawn. Text stays selectable, links and page sizes are kept, and the quality does not change. Form fields and bookmarks from the original files may not carry over, so keep your originals.
When merging helps
Many Australian government upload pages prefer a multi-page document as a single PDF. Home Affairs, for example, asks that documents with more than one page be provided "in a single pdf document" in ImmiAccount. Merging a scanned front and back of a certificate, or several months of statements, into one file keeps the upload tidy and makes it less likely that a page goes missing. See the ImmiAccount upload guide and the myGov and Centrelink upload guide.
Limits
Password-protected PDFs cannot be opened; remove the password in your PDF reader first. Very large files (hundreds of MB) depend on your device's memory. If the merged file is too big for an upload limit, run it through Compress PDF.
Questions
- Is it really free?
- Yes. There is no account, watermark or page limit beyond what your device's memory can handle.
- Are my PDFs uploaded?
- No. Merging happens inside your browser and the files never leave your device.
- Can I merge password-protected PDFs?
- Not directly. Open the PDF with its password, save an unprotected copy, then merge that copy.
