Frequently asked questions

Is there a limit to how many PDFs I can merge?

There’s no hard limit, but very large combined files can take longer to process since everything runs in your browser rather than on a server.

Will the page order be preserved?

Yes, each PDF keeps its internal page order. You control the order of the files themselves using the reorder arrows.

Are my files uploaded anywhere?

No. Merging happens entirely on your device using JavaScript — your PDFs never leave your browser.
