Frequently asked questions

How many PDFs can I merge at once?

There's no fixed limit. Since everything runs on your own computer, it depends on your device's memory. Most laptops handle dozens of files — even large ones — without any trouble.

Are my files uploaded anywhere?

No. The merging happens entirely in your browser. Your documents never leave your device — no server, no cloud, nobody else can see them.

Will the quality change?

No. The pages are copied directly from the originals — no re-rendering or compression is applied. The merged file is identical in quality to the source documents.

Is it free?

Completely free — no account, no watermarks, no limits on how many times you use it.

Can I rearrange pages from different files?

This tool merges whole files in the order you set. If you need to rearrange individual pages from different documents, merge them first, then use the Rotate & Organize tool to reorder pages within the combined file.
