Merge PDF files
Combine several PDF files into a single PDF. Add as many files as you like, drag them into the right order, and download one merged PDF.
Private by design: your files are processed on your device and never uploaded.
How to merge PDF files
- Add two or more PDF files — drop them on the box or tap to choose.
- Drag the files into the order you want. Remove any you don't need.
- Press “Merge PDFs” and download your combined file.
About Merge PDF
Merging is handy when a form asks for one document — for example an application with your ID, certificates and photos as separate PDFs. The pages are copied exactly as they are, so text stays sharp and searchable, and links and form fields keep working.
Questions
Is it safe to merge PDFs here?
Yes. The work happens inside your own browser, so the file is never uploaded to a server — not ours, not anyone's. That makes it safe for contracts, bank statements, ID cards and other private documents.
How many PDFs can I merge at once?
There is no fixed limit. Very large files depend on your device's memory; on a phone, a few hundred pages at a time is comfortable.
Will the quality change?
No. Pages are copied as they are — nothing is re-compressed or turned into pictures.
Can I change the order of the pages?
You can order the files before merging. To reorder individual pages afterwards, use Organize PDF.
Is it really free?
Yes — merging is completely free, with no sign-up, no watermark and no daily limit.
Can I merge PDFs on my phone?
Yes. It works in the browser on Android phones, iPhones, tablets and computers. Nothing to install. It works best in Google Chrome.
