How to combine PDF files
Merge PDF files in three steps, right here.
Add the PDFs to merge
Drop your PDF files on the box or pick them from your device. Each card shows the first page and the page count.
Put them in order
Drag a card by its handle, or focus the handle and use the arrow keys. A card's number is its place in the file.
Merge and download
Keep or drop the first file's title and author, then press Merge. One combined PDF downloads to your device.
Combine multiple PDFs into one file
A contract with its annexes, a report with its appendix or a month of scanned receipts is easier to send, read and print as one PDF. Joining the files means the reader opens a single document and scrolls through it in the order you set.
Merging copies every page exactly as it is. Text stays selectable, images keep their full quality and each page keeps its size and orientation. Nothing is converted, flattened or redrawn along the way.
It works the same in any modern browser on Windows, Mac, Linux, Android or iPhone, so there is no app or Adobe Acrobat to install. Bookmarks and fillable form fields from the original files may not carry over.
What this PDF merger does well
Merge and reorder
Put the files in any order before merging. Drag the numbered cards, or move them with arrow keys.
Merge PDF with preview
First-page thumbnails and page counts help you spot a duplicate or an old version before you merge.
Nothing to install
Merge PDF files right in this tab on Windows, Mac or a phone. No upload, no app and no Acrobat.
PDF metadata, your call
Keep the first file's title, author, subject and keywords in the merged PDF, or leave them out.
Merge and compress
Turn on Compress PDF to pack the merged file's structure tighter. Pages and images look the same.
Free and unlimited
Combine PDF files for free as often as you like. No account, no daily cap, no logo on your pages.
Is it safe to merge PDFs online?
Yes. Your files never leave your device.
Processing
Your PDFs are joined by code running in this tab, in your device's memory. They never go online.
Storage
No copy is saved on our side or yours. Close or refresh the page and the added files are cleared.
Account
No sign-up and no email. Merge PDFs as often as you like; nothing about your files is tracked.
Questions about combining PDFs
How do I merge two PDF files?
Add both files, check which one should come first and press Merge. The second file's pages follow straight after the first.
Can I merge PDF files for free?
Yes. Merging is free with no account, no daily limit and no watermark, however many files you combine.
How do I combine PDF files on a Mac?
Open this page in Safari, Chrome or Firefox on your Mac and add the files. There is nothing to install; it works as on Windows.
Can I combine PDFs on my iPhone?
Yes, in Safari or any modern mobile browser. Pick the files from the Files app, then press and drag a card's handle to move it.
Can I change the order before merging?
Yes, any time before you press Merge. Drag the cards by their handle, or focus a handle and use the arrow keys.
Can I merge large PDF files?
Yes. Each file can be up to 100 MB. Very large batches are quicker when merged in a few rounds, then merged once more.
Can I merge password-protected PDFs?
Not while they are locked. Open the file with its password and save an unlocked copy first, then add that copy here.
