Combine PDFs

Merge PDF files online — free and private

Combine multiple PDFs into a single document right in your browser. Add up to 5 files, reorder them however you like, and download one merged PDF — everything happens on your device, so your documents are never uploaded. Free, no account required.

How it works

1. Add your PDFs — drag and drop up to 5 files, or choose them from your device.
2. Reorder — drag each file into place, or use the up and down arrows.
3. Merge & download — one combined PDF is produced and saved to your device.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Merging happens entirely in your browser — your files and the combined result never leave your device.

How many files can I merge?

Up to 5 PDFs at once, with a total of 50 pages and a maximum of 25 MB per file.

What happens to fillable form fields?

The merged output is a plain PDF — form fields are flattened into the page content so the combined file opens consistently everywhere.

Does it cost anything?

No. Merging is free, with no accounts, no sign-up, and no watermarks.
