Merge PDF files
Put several PDFs into one file: a proposal and its appendix, a set of signed pages, or invoices for the month. Images can go in as pages too.
Your files never leave your computer. They are processed in this browser tab.
How to use it
- Drop your PDFs, or tap the box to pick them. JPG and PNG images are fine too.
- Put them in order with the arrows. The top file comes first.
- Press Merge and download one PDF.
Free, no account. The page loads once, then the work happens in your browser. We don't receive the file, its name or anything in it.
Questions
Are my PDFs uploaded?
No. The file is opened by this browser tab and processed on your computer. There is no upload step, so we never see the file or its name, and closing the tab throws the work away.
Does merging change the quality?
No. Pages are copied as they are, with their text, fonts and images untouched. Images you add become one page each at their own size.
Can I merge password-protected PDFs?
Not reliably. Open the file with its password and save a copy without one first, then merge the copy.
Is there a limit on files?
Up to 50 files and 300 MB together, because the whole document is built in your browser's memory.
