Are PDF documents uploaded to external servers?

No. PDF files are merged directly inside your browser memory using pure JavaScript.

Is there a limit on files or size?

There is no fixed limit. Very large files depend on your device's memory; most documents of a few hundred pages merge in seconds.

Can I merge only some pages of a file?

Extract the pages you need with Split PDF first, then merge the result.

What if one file won't open?

It is skipped and named in a message, and the other files are still added. It is usually damaged or password-protected.

Will merging change the quality of my PDFs?

No. Pages are copied without being re-rendered.

About Merge PDF

Combine two or more PDF files into one document. Add files, put them in the right order, preview any file, and download a single merged PDF. Your files are merged in your browser and never uploaded.

Ordering and previewing

Files are merged top to bottom in the order shown. Use the up and down arrows to move a file, and click any file to preview its pages before merging. Each file shows its page count and size, so you know how long the final document will be.

You can keep adding files after the first batch; new files go to the end of the list.

What is kept

Pages are copied as they are, including text, images, and links, so the merged file looks the same as the originals. Bookmarks from the individual files are not combined.

Password-protected PDFs cannot be opened, so they are skipped with a message. Remove the password in your PDF reader first, then add the file again.

Common uses

Application packets: Combine a cover letter, resume, and references into one file.
Scanned documents: Join pages that were scanned as separate files.
Receipts and expenses: Put a month of receipts into one PDF for accounting.
Reports: Merge chapters or sections written by different people.
