I find it difficult to encrypt multiple PDF files at the same time securely. When attempting to add several documents at once, the tool doesn't seem to work properly. I can only upload and edit one file at a time, which is time-consuming and inefficient, particularly when I have to encrypt and secure large amounts of PDFs. Moreover, it is inconvenient to have to monitor each process individually instead of letting them all run simultaneously. This lack of batch processing is really a hindrance to the effective and efficient use of the tool.

The PDF to Secure PDF tool from PDF24 can solve this problem by offering the ability to conduct batch processing. This function allows you to encrypt and secure multiple PDF files at once. Simply upload all the files you want to edit at once and the tool encrypts them in one fell swoop, saving time and increasing efficiency. You do not have to monitor each process individually; the tool performs all encryption actions simultaneously. Thus, you can quickly and efficiently encrypt and secure large quantities of PDFs. Furthermore, the tool's automatic deletion function ensures the security of your data after the encryption process.
