Frequently asked questions

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

No hard limit — you can merge as many PDF files as you like in one go.

Are my files uploaded to a server?

No. Merging happens entirely inside your browser using JavaScript — your files never leave your device.

Will the quality of my PDF change?

No, merging simply combines the original pages as-is with no re-compression or quality loss.
