What the Merge PDF tool does
Merge PDF takes two separate PDF files and joins them into a single document, keeping every page in the order you set. It is handy when you want to attach an appendix to a report, combine a signed page with the original form, or put two scanned chapters into one file. Because the whole thing happens in your browser, it works the same on a laptop, tablet, or phone with no software to install.
How to merge two PDFs
- Open the tool and drop your first PDF into the box, or click to browse for it. The box reads “Drop your PDFs here (in the order to merge),” so the order matters.
- Add the second PDF. The file you placed first becomes the front of the combined document.
- Click Merge PDF. The pages are copied and stitched together right on your device.
- Download the new single PDF. Your two original files stay exactly as they were.
Why merge here
It is fast: the merge runs locally, so there is no upload wait and no progress bar crawling while a server processes your file. It is private: contracts, bank statements, and ID scans never leave your computer, which matters more than most online mergers admit. And it is genuinely free with no account, no email, and no watermark stamped on your result.
This page handles two files per merge, which fits the vast majority of quick jobs. Working through a big stack of documents instead? The free BulkPro desktop app from the same team is built for batch merging many files at once.
Quick tips
Rename your files with a 1 and 2 prefix before dropping them in if you want to be certain of the order. And if a PDF is password protected, unlock it first, since a locked file cannot be read for merging.
Frequently asked questions
- How many PDFs can I merge at once?
- This tool combines two PDFs per merge, which covers most everyday needs like joining a cover letter to a resume or two scanned sections. If you need to stitch together dozens or hundreds of files in one go, the free BulkPro desktop app by the same team (Bilgetek) handles batch merging.
- Will the page order be kept?
- Yes. The files merge in the order you add them, and all pages from each PDF are copied in their original sequence. The drop box even says "in the order to merge," so add the file you want first, then the second one.
- Are my PDF files uploaded anywhere?
- No. The merge runs entirely in your browser using your device's own processing. Your documents are never sent to a server, which makes it safe for contracts, invoices, and anything private.
- Does merging reduce quality or change my PDFs?
- No. The tool copies the original pages exactly as they are into a new combined document, so text stays selectable and images keep their quality. The two source files are left untouched.
