Why combine PDF files?
Keeping related pages in one file is simply easier to send, upload and store. Instead of attaching five separate PDFs to an email, you combine them into one. Common uses: joining scanned document pages, merging invoices or statements, putting a cover letter and resume together, or combining form pages before an upload that accepts a single PDF.
Is a PDF merger, PDF joiner and PDF combiner the same thing?
Yes. A PDF merger, PDF joiner and PDF combiner all do the same job: they take several PDF files and join them into one. Different tools use different names, but the task is identical, and that is exactly what this tool does.
Do my files get uploaded?
No. The merge happens entirely in your browser using JavaScript, so your PDFs are never sent to us or any server. That matters for private documents like contracts, bank statements or IDs. It even works offline once the page has loaded.
Need the opposite? Split a PDF
If you want to pull pages out of a PDF or break one into parts, use our Split PDF tool. To turn images into a PDF first, try Image to PDF.
