Frequently Asked Questions
How do Hong Kong users password protect PDFs without paying for software?
There are no restrictions — PDF password protection is completely free for Hong Kong users in Central, Kowloon, and New Territories and across Hong Kong — no signup, no watermark, with 256-bit AES encryption.
Does password protection meet PDPO (Personal Data Privacy Ordinance) requirements in Hong Kong?
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 Hong Kong.
Can I open the protected PDF with GovHK, eTAX, and Hong Kong government online 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 salaries tax documents before uploading to GovHK or eTAX in Hong Kong?
Yes — the GovHK portal and eTAX digital services in Hong Kong enforce upload size limits for Salaries Tax return attachments. Compressing your BIR60 tax returns, HKID scans, and employer's tax documents to under 2 MB prevents upload errors and ensures your Hong Kong Inland Revenue submission is accepted.
