Frequently Asked Questions
How do Iranian users password protect PDFs without paying for software?
There are no restrictions — PDF password protection is completely free for Iranian users in Tehran, Isfahan, and Shiraz and across Iran — no signup, no watermark, with 256-bit AES encryption.
Does password protection meet Iran data protection law requirements in Iran?
256-bit AES encryption is the highest standard for PDF security and is recognised by banks, government agencies, and data protection authorities worldwide, including in Iran.
Can I open the protected PDF with Iran e-government portals, Tax Administration, and digital services systems?
Absolutely — password-protected PDFs are standard format compatible with all PDF viewers. The recipient needs only the correct password to open the file.
Can I compress my tax documents before uploading to my.tax.gov.ir in Iran?
Yes — the my.tax.gov.ir portal and Shahrvand digital services in Iran have upload size limits for tax return documents. Compressing your Maliati declarations, Melli Card documents, and supporting receipts to under 2 MB prevents submission errors and ensures your Iranian tax filing is accepted.
