Combine PDF files into one, privately
Put several PDFs together in the order you choose. Merging happens on your own device, so contracts, statements and scans never leave it.
Your PDFs are merged on this device and never uploaded. We don't see, store or log your files.
How it works
- Tap Choose files and select two or more PDFs.
- Use the arrows to put them in the order you want.
- Tap Merge PDF. The files are combined on your device.
- Download the merged PDF, or tap Share to save it.
Why merge PDFs here
Most PDF mergers upload your documents to a server. This one combines them in your browser instead, so nothing about your files is sent anywhere.
There is no account, no watermark and no daily limit.
What to expect from the merged file
Merging copies pages exactly as they are, without compressing anything, so the result is roughly the sum of the originals: three 2 MB PDFs make a file of about 6 MB. If that is too big to email (Gmail allows 25 MB, Outlook.com 20 MB), run it through Compress PDF afterwards.
Every page keeps its own size and orientation, so an A4 page next to a US Letter page stays exactly as it was.
Limits to know about
Password-protected PDFs can't be merged until the password is removed. Bookmarks and fillable form fields from the original files may not carry over to the merged PDF.
Combining many large files needs a lot of memory; if a phone struggles, merge in smaller batches or use a computer.
Frequently asked questions
Can I change the order of the files?
Yes. Before merging, use the up and down arrows next to each file. The merged PDF follows that order exactly.
Will merging reduce the quality?
No. Pages are copied as they are and nothing is re-compressed, so text and images look exactly like the originals.
Are my PDFs uploaded?
No. Everything happens in your browser on your own device. Your files are never sent to us or anyone else.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and Samsung Internet. Choose the PDFs from Files or Google Drive, and use Share to save the merged file.
