How to use it
- 1Drag in the PDFs you want to combine, or click to upload them all at once. You can add more later.
- 2Use the move-up and move-down buttons to set the order. Drop any file you don’t need.
- 3Hit merge and they’re joined into a single PDF in that order.
- 4Check the combined file in the preview and download it — that’s it!
Handy tips
- You need 2 or more PDFs for the merge button to light up — with just one, there’s nothing to join.
- The merge order follows the list exactly, top to bottom. Give it one last check before downloading.
- A password-protected or damaged PDF in the mix can stop the merge. Remove that file and try again.
Sort the order before you merge
The trick to a clean merge is settling the order before you upload. Prefixing filenames with numbers — "01_cover", "02_body" — means a batch of files lands in roughly the order you want, so there's less to fix by hand. Setting a naming rule right when you save from a scanner app pays off especially well.
Once they're in, you can still shuffle them with the move-up and move-down buttons. The merge follows the list top to bottom exactly, so drop any stray file with the remove button and just line up the rest. Getting into the habit of checking the first and last page in the preview before downloading all but eliminates mistakes.
Pulling scattered files into one — real uses
It fits well for binding a separately received cover, body, and appendix into one submission-ready file, or rejoining a contract that got split into pieces mid-scan. It's just as handy for arranging meeting materials in presentation order, or gathering monthly statement and receipt PDFs into a per-quarter set.
This tool joins the pages of each PDF as they are, without redrawing them. So the original text selection, image quality, and page sizes all carry through the merge undamaged. Because your text never turns into an image, you can combine documents you'll need to search or copy from with full confidence.
Why merging here is safe
The biggest worry when combining sensitive documents — contracts, statements — is a file leaking out. This tool does the entire merge inside your own browser, so the PDFs are never uploaded to a server. The whole process runs on your device to the point that even a brief drop in your internet connection won't stop the files you've already added from being joined.
Your original files aren't touched either. Merging builds one brand-new file that you download separately, so the PDFs you started with stay right where they were. That means you can freely reorder them, or drop a few and merge again, without any risk of damaging the originals.
Frequently asked questions
No. Merging happens entirely on your device, so the files are never sent anywhere. Your originals stay as is and you just download the new combined file.
There's no fixed cap on count or size, but since everything runs in your browser, a very large combined size can strain your device's memory. For heavy files, it's best to slim them down with PDF compress first, then merge.
Yes. Even with a mix of portrait and landscape, each page merges at its own orientation and size. It won't force them uniform, so if you want a tidy result, align the orientation per file before merging.
There’s no fixed limit. That said, since everything runs in your browser, a lot of files or very large ones may slow down depending on your device.
Yes. Use the move-up and move-down buttons in the list to arrange them, then merge. Drop anything you don’t need with the remove button.
This tool combines whole files. If you only want certain pages, pull them out first with the PDF split/extract tool, then merge them here.
