Merge PDF
Combine multiple PDF files into one. See every page, drag pages into any order or remove them, then merge — in your browser, never uploaded.
Combine contracts, invoices, reports or scanned pages into a single PDF in seconds. Add your files, put them in the right order and download one merged document.
Your PDFs are merged on your own device, inside your browser. They are never uploaded to a server, so this tool is safe to use with confidential documents.
How to use Merge PDF
- Click “Choose PDF files” or drop your PDFs onto the page.
- Put the files in order with the arrow buttons, or drag them.
- Optional: in the page strip, drag pages (or use ‹ ›) to change their order, and remove pages you don’t need.
- Click “Merge PDF” and download your new document.
Features
- No upload: files are merged on your device and never leave it.
- No sign-up, no watermark and no limit on the number of files.
- See every page: drag pages from different files into any order, or remove them.
- Original quality: pages are copied as they are, not re-compressed.
- Works on Windows, Mac, Linux, Android and iPhone in any modern browser.
Frequently asked questions
Is it free to merge PDF files here?
Yes. Merge PDF is completely free, with no sign-up, no watermark and no daily limit.
Are my files uploaded?
No. The files are read and merged by your own browser. Nothing is sent to our servers, and the result is created on your device.
How many PDFs can I merge at once?
There is no fixed limit. Very large files (hundreds of MB) may be slow on phones because everything happens on your device.
Can I change the order of pages, not just files?
Yes. After adding files, every page appears in a strip. Drag a page by its grip or use the ‹ › buttons to move it — pages from different files can be mixed in any order.
Can I leave out some pages?
Yes. Click × on a page to remove it from the merged PDF. Reset pages brings all pages back in their original order.
Will the quality change?
No. Pages are copied exactly as they are, including text, images, links and form fields.
Can I merge password-protected PDFs?
Not directly. Remove the password first (you need to know it), then merge the unlocked file.
