Frequently Asked Questions
How secure is the encryption used?▼
We use standard AES (Advanced Encryption Standard) encryption, the same cryptographic standard banks and governments rely on to protect sensitive data.
Apa yang terjadi jika saya lupa kata sandinya?▼
The file becomes permanently unreadable without it. We don't keep a copy of your password or your document, so there's no way for us to recover it for you — store it somewhere safe.
Does password protection also stop people from printing or copying?▼
Menetapkan kata sandi terbuka mengharuskan siapa pun untuk memasukkannya sebelum mereka dapat melihat file sama sekali, termasuk pencetakan dan penyalinan, karena mereka tidak dapat mengakses konten tanpa membukanya terlebih dahulu.
Can I remove the password later if I no longer need it?▼
Yes, use Unlock PDF and enter the password to strip it back off whenever the file no longer needs to be restricted.
Apakah kata sandi saya dikirim ke mana pun saat saya mengaturnya?▼
No, the encryption is applied entirely inside your browser, so the password you type never leaves your device.
