Merge PDFs

Combine several PDF files into a single document, in the order of your choice.

Example:

How it works

Useful for combining several scanned documents into a single file to send — for example a resume and a cover letter before applying for a job, or the invoices received in a month before passing them on to your accountant. Add your PDF files, reorder them if needed, then click "Merge" to get a single downloadable PDF.

Can I change the order of the files before merging?

Yes. Each added file appears in a list with "↑" and "↓" buttons that let you move it up or down; the order shown in the list is the one used for the merge.

Is there a limit on file size or number?

The tool doesn't impose an artificial limit on the number or size of PDF files: at least two files are required to start a merge. Beyond that, the practical limit depends on the memory available in your browser for handling very large documents.

The merge happens 100% locally in your browser via WebAssembly: your documents, even sensitive ones (resume, invoices), never leave your device.
