Questions people actually ask

Can I merge without an account?

Yes. The free plan joins up to 3 PDFs. Larger batches are a Pro and Business limit, not a separate product.

Will bookmarks and forms survive?

Pages are appended with pdfcpu. Interactive forms and outlines are not a goal of this build and may be dropped.

What if one file has a password?

The merge stops. Unlock it locally and upload the unlocked copy. Sheafkit does not ask for PDF passwords.
