Why convert ASEC to PDF?
An ASEC file is an encrypted loopback image holding a moved Android app - not a document, not text, and not any format with renderable content. PDF is a page-description format for text and images. Even if decryption were possible, the contents would be compiled Android application code and data, not anything that maps to a PDF page.

Frequently asked questions
Are ASEC files documents of any kind?
No - they are encrypted Android app containers holding compiled application code and data, not any form of document.
Why do converter sites list ASEC to PDF as an option?
Those sites list format pairs based on names, not technical feasibility; no real converter handles this combination.
Can I recover the app from an ASEC file if I still have the original phone?
Not via the ASEC file - reinstall the app from the Google Play Store or its original APK source instead.
