How to merge PDF files into one
Choose two or more PDFs and Merge PDF joins them into one new file, merged.pdf. The files go in the order you choose them: the first file you pick comes first, and each next file follows. Pages inside each file keep their order. Each page is copied as it is, so photos keep their quality and text stays selectable. You cannot drag files into a new order after you pick them, and merging does not sort them by name. Merging does not make the file smaller. To shrink it, use Compress PDF. Searching for how to combine PDF files? This is the tool. Use it to join scans into one file, to bundle a report with its appendix, or to send one attachment instead of five.
Your files stay on your device. They are never uploaded. We add no watermark and no page of our own. When you close the tab, the copy in your browser is gone. Your originals are not changed.
Free, with no account, no daily limit and no page limit. Your device needs enough memory to hold all the files. If it runs out, try fewer or smaller files. You can merge as many files as you like, in as many sessions as you like.
If you have not picked any files, the page asks you to choose one. A password-protected PDF cannot be merged, and we do not guess passwords. Unlock it first with Unlock PDF, using the password you already know. Then add the unlocked file here with the others. To pull the pages apart again later, use Split PDF.
How to use this tool
- Choose your file. It never leaves your device.
- Pick a setting, if the page has one.
- Download your new file.
Common questions
Which file comes first when I merge PDFs?
The first file you choose. The rest follow in the order you chose them, and pages inside each file keep their order. If the order is wrong, choose the files again.
Is it safe to merge PDFs online?
Yes. Your files never leave your device. You can check in your browser's network panel: no upload appears. Only PDF to Word, OCR and heavy compress send files to our server. Your originals are not changed.
Can I merge a password-protected PDF?
Not directly. Unlock it first with Unlock PDF, using the password you already know. Then add the unlocked file here with the others.
Is Merge PDF really free?
Yes. No account, no daily limit, no watermark. You can merge as many files as you like.
