Merge PDF

How to use Merge PDF

1. Select your files in the private workspace above. Supported inputs: PDF.
2. Review the settings, then start. The workspace uploads and processes your files on the server.
3. Check the output and download it. Delete files when finished, or let them expire automatically after one hour.

Useful to know

Combine the selected PDF documents into one file. Move files up or down in the list before starting: their order determines the final page sequence.

Review the first and last page of each source after merging. Password-protected inputs are rejected.

Changing a signed PDF can invalidate its digital signature.

Supported formats and limits

Up to 50 MB per file. Up to ten files per job; ordinary image and PDF jobs have a 100 MB combined limit. Outputs use PDF format. Busy queues may ask you to try again shortly.

Do I need an account?

No. Every tool works for guests. Your favorites and saved settings stay on this device and do not include file contents.
