    FAQ

    What users need to know for merge pdf.

    How long are files kept?

    Jobs expire automatically after the configured retention window. The default project setup uses 2 hours.

    Do I need an account?

    No. The app tracks only a temporary browser session cookie so you can refresh and still download the result.

    Will every file convert perfectly?

    Simple files are reliable. Complex layouts, scans, forms, or macros can still need manual cleanup after conversion.
