A premium offline desktop utility designed to secure confidential PDF documents. It allows you to encrypt single or multiple PDF files at once with a custom password, blocking unauthorized access.

Privacy & DPDP Compliance: Operates 100% locally and offline. Passwords and documents are processed locally in RAM and are never transmitted over the network. Safe for securing highly confidential data (salary slips, tax sheets, audit records).

Key Features:

• Batch Encryption: Secure one or dozens of PDF files simultaneously with a unified password.
• Masked Password Entry: Input field with a Show/Hide toggle button to verify typed passwords safely.
• Auto-Suffix Renaming: Saves encrypted copies as EffCorp_<filename>_encrypted.pdf to prevent overwriting original files.
• Summary Metrics: Live counts of total files and projected combined output size (MB).
