Need to combine several PDFs into one file? You do not need paid software or risky uploads. Here is how to merge PDFs for free, privately, in your browser.

Why merge PDFs?

Combining PDFs is handy for joining invoices, scanned contracts, reports or chapters into a single, easy-to-share document. One file is simpler to email, print and store than a dozen separate ones.

How to merge PDF files

Everything happens locally in your browser using a secure PDF library, so your documents are never uploaded to a server. Need the opposite? The Split PDF tool extracts a page range into a new file.

Tips

Put your files in the right order before merging, and if the result is large, you can shrink images first with the Image Compressor before converting them with JPG to PDF.

Frequently asked questions

Is it safe? Yes — your PDFs never leave your device.

Is there a file limit? You can merge multiple files; very large documents depend on your device’s memory.
