PDF Tools

Merge multiple PDF files into one document

Click to upload PDFs

Select multiple files to merge

PDF (Portable Document Format) is the universal standard for sharing documents. Our PDF Tools let you merge multiple PDF files into one combined document — entirely in your browser.

How to merge PDFs

Click the upload area and select two or more PDF files. They will be listed in order. Click Merge PDFs and once complete, download the combined file. The order of the pages follows the order you selected the files.

Why merge PDF files?

Combining PDFs is useful in many situations:

Combining multiple reports into one document
Merging scanned pages into a single file
Packaging invoices and receipts together
Combining chapters of a book or manual
Sending fewer email attachments

Is it safe to merge PDFs here?

Yes. All PDF processing is done entirely within your browser using the pdf-lib library. Your files are never uploaded to any server. Your documents remain completely private.
