Merge PDF Free, No Sign-Up, No Watermark

1. Add your PDFs. Drop them onto the box above, or use Choose PDF files. Add as many as you need, all at once or one after another.
2. Put the pages in order. Every page of every file appears in one grid. Drag pages, or a whole selection, to where they belong. Rotate or delete any page on the way.
3. Choose Download. You get one PDF with all the pages in the order shown, named after the first file, for example report-organized.pdf.

Each file gets a letter, and each page a label such as A3 (file A, page 3), so you can always tell where a page came from. Because the pages of all your files sit in one grid, you can interleave them: put page 1 of one file between pages 4 and 5 of another, or move a cover page from a second file to the front.

Pages keep their own size, so a merged file can mix A4, Letter and landscape pages. If you add the wrong file, Undo takes it out again.

Your files are processed in your browser and are never uploaded to our servers. Your browser reads each file into memory on your device, puts the pages together there, and saves the merged file to your downloads. No sign-up. With nothing uploaded, there is nothing an account would need to hold. No watermarks.

• Password-protected PDFs can't be added. Remove the password in your PDF reader first.
• Bookmarks and some interactive form features of the original files may not be kept in the merged file.
• How much you can merge at once depends on your device's memory.

Is there a limit on how many files I can merge?

No download limits. How many files you can open at once depends on your device's memory: if the browser tab slows down, merge in smaller batches, then merge the results.

Can I merge PDFs with different page sizes?

Yes. Each page keeps its own size and orientation in the merged file.

Can I change the order after adding the files?

Yes. Drag any page or selection to a new position, or use the keyboard: focus a page, press Space to pick it up, move it with the arrow keys and press Space again to drop it.

What is the merged file called?

It takes the name of the file whose page comes first, with -organized added, for example invoice-organized.pdf.

Does merging work on a phone?

Yes. Tap pages to select them, and press and hold a page to drag it.
