Tambahkan Kata Sandi ke PDF
Enkripsi PDF Anda agar hanya bisa dibuka dengan kata sandi yang Anda tetapkan.
Cara kerjanya
1. Unggah PDF Anda. 2. Ketik kata sandi dan konfirmasi. 3. Unduh — file terenkripsi (AES-256) sehingga hanya bisa dibuka dengan kata sandi tersebut.
Apakah kata sandi saya dikirim ke suatu tempat?
Tidak — enkripsi sepenuhnya terjadi di browser Anda. File dan kata sandi Anda tidak pernah meninggalkan perangkat Anda.
Bagaimana jika saya lupa kata sandinya?
Tidak ada cara memulihkannya — enkripsinya nyata, jadi kata sandi yang terlupa berarti file tidak bisa dibuka oleh siapa pun, termasuk kami. Simpan di tempat yang aman.
Enkripsi apa yang digunakan alat ini?
AES-256, standar kekuatan enkripsi PDF saat ini, melalui mesin qpdf open-source yang banyak digunakan dan berjalan di browser Anda.
Does this work on a mobile browser?
Yes — it's a regular web page, not an app, so it works the same way in a mobile browser as on desktop. Tap to pick the file, set a password, and download the encrypted result — the encryption still happens entirely on your device.
Does this restrict printing or copying, not just require a password to open?
No — it's a single password that's required to open the file. Once someone has entered it, they can print, copy, and edit like normal; there's no separate owner password or permission controls that limit what an already-authenticated reader can do. Worth knowing anyway: those "disable printing/copying" options other tools offer are only honored by well-behaved PDF readers — anyone can strip them by printing the file to a new PDF.
What makes a good password for this?
Something reasonably long that isn't a guessable word — not your birthday, not "password123". We only require 4 characters minimum so we don't block anyone, but since there's no permission system backing this up, that password is the only thing standing between someone and the file. Treat it like a real password.
