merging PDF file and disappeared digital signature

[deepak_8943]

Dear Acrobat team for Windows,

We are currently working in the pressure vessel manufacturing industry, where our daily activities involve preparing reports that require client signatures. However, we are encountering issues when attempting to merge these daily reports into a single dossier file. Specifically, the digital signatures are being removed from the final merged PDF file.

We kindly request your guidance and any valuable input you can provide to help us resolve this issue. We have also tried using PDF portfolios, but this approach has not yielded the desired results.

Thank you for your assistance.

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Signed PDF cannot be merged without losing their integrity, so the portfolio is your only choice: https://helpx.adobe.com/acrobat/using/overview-pdf-portfolios.html
