Frequently Asked Questions

How many PDFs can I merge at once?+

There's no hard limit from the tool, but very large files or a large number of files may be slower since everything is processed in your browser's memory.

Are my files uploaded to a server?+

No. Merging happens entirely in your browser using the pdf-lib JavaScript library. Your files never leave your device.
