Local PDF Tools
Merge PDF files without uploading them
Your PDFs are combined right here in your browser tab — they are never sent to a server.
Is it safe to merge confidential PDFs online?
Only if the files never leave your computer. Most online PDF mergers upload your documents to their servers to combine them.
- A client contract, a payslip or a patient letter ends up on a server you know nothing about.
- Your agreement with a client or employer may not allow that at all.
- And the convenient services bill you every month for a two-minute job.
Local PDF Tools merges the files on your own device instead.
What do you get by merging PDFs locally?
Your files are processed on your device and never uploaded. There is no copy on anyone's server, so there is nothing to delete afterwards and nothing to explain to a client.

How do you merge PDF files without uploading them?
Add your PDFs to the merge tool on this page, put them in order, and download one merged PDF — every step runs inside your browser.
-
01
Add your PDFs
Drop two or more PDF files onto the tool, or click it to choose them. A password-protected PDF asks for its password.
-
02
Set the order
Drag the files into the order you want. Thumbnails of every page show the merged result before you merge.
-
03
Merge
“Merge into one PDF” combines the files in a background worker on your device.
-
04
Download
One PDF with every page, in your order, is saved straight to your computer.
Where does your file go?
With an online PDF service, to their server and back. Here, nowhere: it is read, merged and saved on your device.
| Online PDF services | Local PDF Tools |
|---|---|
| Your files are uploaded to their servers | Your files are read by your own browser |
| Merged there, then downloaded back to you | Merged on your device, in a background worker |
| Deleted later — on their schedule, under their policy | Nothing to delete: no copy ever left your computer |
| Monthly or yearly subscription for regular use | $29 one-time. No subscription. |
Can the same page do more than merge?
Yes. Once your files are added, the same page can also split a PDF, rotate, delete or reorder pages, export pages as JPG or PNG images, and fill in and sign a PDF — all on your device, without uploading anything.
Questions about merging PDFs locally
Are my PDFs uploaded when I merge them with Local PDF Tools?
No. Your files are processed on your device and never uploaded. Local PDF Tools merges PDF files inside your web browser, so no copy of them exists on any server.
Can I merge PDF files offline?
Yes, once the page is open. Once loaded, every tool works offline — no internet connection needed. After the Local PDF Tools merge page has loaded in your browser, you can disconnect from the internet and keep merging PDFs in that tab. Opening or reloading the page needs a connection.
How large can the PDF files be?
Local PDF Tools merges two or more PDF files at a time, each up to 50 MB and 300 pages. During the free trial, each file can have up to 50 pages.
Can I change the order of the PDFs before merging?
Yes. In Local PDF Tools you drag the files into the order you want, and thumbnails of every page show the merged result before you download it.
Can I merge password-protected PDFs?
Yes, if you know the password. Local PDF Tools asks for the password when you add a protected PDF and opens the file in your browser — the password is not sent anywhere either.
Can I merge PDFs on a phone?
Yes. The Local PDF Tools merge page works in a mobile browser as well as on a computer: tap the drop area to pick PDF files from your phone.

For a start, yes. In Local PDF Tools, the first 5 operations are free, on files up to 50 pages — no account, no email, no card. After that, $29 once unlocks every tool permanently. There is no recurring charge and nothing to cancel.
