What is Merge PDF files?
Merging PDFs is the job that comes up most often when submitting paperwork: your certificate is one file, your ID another, your application a third, and the form only accepts a single upload. This tool joins them in the order you arrange, keeping every page exactly as it was.
What separates it from most free merge sites: your files never leave your machine. The browser reads them, joins them and hands back the result. This site server does exactly one thing, which is send you the page. It does not receive, see or store anything you drop in.
That matters in practice, not just as a slogan. Personal documents, contracts and bank statements are precisely the things you cannot verify a stranger site did anything sensible with after receiving them. Here you can verify it: load the page, disconnect from the internet, and the merge still works.
The order in the list is the page order in the result. Use the arrows to move a file, the cross to drop one. There is no limit on how many files you add beyond your own machine memory.
How to use
- Drop or select several PDF files at once.
- Click the drop zone again to add more files.
- Use the up and down arrows to reorder, which sets the page order in the result.
- Click the cross to remove a file you do not want.
- Press merge and the finished file downloads itself.
Frequently asked questions
Does merging reduce quality?
No. Pages are copied across intact, with no re-compression and no image rebuilding. Text stays selectable and images keep their original sharpness.
How many files can I merge?
There is no fixed limit. The real limit is your machine memory, since everything happens in the browser. A few dozen files of a few MB each is routine; several hundred MB in total may struggle on an older machine.
What about password-protected files?
Files that merely restrict printing or editing merge fine. Files that need a password just to open do not, so remove the password in a desktop PDF reader first.
Will the result carry a watermark?
No. No logo, no faint promotional text, no added cover page. The output has exactly as many pages as the files you put in.
