How many files can I merge at once?

There is no fixed limit. The tool runs on your own machine, so the practical ceiling is what your browser can comfortably hold in memory.

Can I merge only part of a file?

Yes. Open the pages view and take the pages you want from each file before you merge, rather than merging everything and deleting afterwards.

Are my files uploaded?

No. Merging happens in this browser tab and the files never leave your machine.

Download the combined PDF as one file.

What it does

Merge PDF files, in full.

Add every file you want combined, drag them into the order you want, and download one PDF. Each file keeps its own page size and orientation, so a landscape scan dropped between two portrait reports stays landscape. If you only want part of a file, pick its pages before you merge rather than merging and then deleting.

Combine any number of PDFs into a single document
Drag the files into the order you want them read
Take only the pages you need from each file

This tool runs entirely inside your browser tab. The file never leaves your machine, there is nothing to sign up for, and nothing you download carries a watermark.
