Combine PDFs into one polished document. Reorder files and pages, rotate or drop what you don't need, then export a single file — right in your browser.
Files in your merge
Drag cards to reorder. The order here is the page order of the result.
How to merge PDFs
1
Add your PDFs
Drag files onto the drop zone or click to browse. Every file gets a live first-page thumbnail and its page count.
You can add up to 20 files per merge.
2
Arrange files and pages
Drag the cards to set the order, or open a card to rotate and delete individual pages. What you see is the order of the result.
Use the arrow buttons for precise, keyboard-friendly moves.

Merge and download
Choose your options, hit Merge, then download the single combined PDF. Everything happens on your device.
Frequently asked questions
How many PDFs can I merge at once?
Up to 20 files per merge, with a 500 MB limit per file.
Are my files uploaded to a server?
No. Merging runs entirely in your browser with JavaScript — your documents never leave your device.
Does merging reduce quality?
No. The default “Keep original” mode copies pages losslessly, so text and images stay exactly as they were.
Can I reorder pages?
Yes. Drag file cards to reorder whole documents, and expand a card to reorder, rotate, or delete individual pages.
Can I add page numbers or bookmarks?
Yes. Turn on page numbers and bookmarks in the options to add numbering and a clickable table of contents for every file.
Can I merge password-protected PDFs?
Unlock them first with our Unlock PDF tool, then merge. Protected files are flagged so you can fix them before merging.
Is there a watermark?
Never. Pixia adds no watermarks and never asks you to sign up.
Does it work on mobile?
Yes. The tool is fully responsive and works on phones, tablets, and desktops.
