Merge several PDFs without uploading them

To combine several PDFs, add the files, check each thumbnail, put them in the order you want, then export a single document. Processing happens in your browser.

Add the PDFs. The file name and page count help you tell each document apart.
Move the files or pages into their final order and use the preview to check anything hard to recognise.
Run the merge, open the downloaded file and check the pages where the documents join.

Limits to know: up to 20 files, 100 MB and 200 pages in total per run. Interactive forms, digital signatures or advanced features of some PDFs may not be kept exactly as they were after rebuilding.

Frequently asked questions

Can I change the order before merging?

Yes. Documents and their pages stay identifiable before export, so you can check the final order.

Are the PDFs uploaded to a server?

No. This tool reads and rebuilds the files in the browser. Only a usage counter may be sent, never the PDF or its name.

Is merging free?

Yes. Three successful exports are available without an account, across all local tools. A confirmed free access then lets you continue.
