Frequently asked questions

Are my PDF documents uploaded to a remote server?

No. All PDF merging operations execute locally within your browser using WebAssembly and pure client-side PDF libraries. Your files never leave your device.

Is there a limit on the number of PDFs I can merge?

You can merge as many files as your device’s memory permits. We recommend keeping individual files under 100MB for optimal performance.
