Ongeza Nenosiri kwenye PDF
Ficha PDF yako ili iweze kufunguliwa tu kwa nenosiri unaloliweka.
Jinsi inavyofanya kazi
Pakia PDF yako, andika nenosiri na ulithibitishe, kisha upakue — faili imefichwa (AES-256) hivyo inaweza kufunguliwa tu kwa nenosiri hilo.
Je, nenosiri langu linatumwa mahali popote?
Hapana — ufichaji unafanyika kabisa kwenye kivinjari chako. Faili yako na nenosiri lako havitoki kwenye kifaa chako.
Je, ikiwa nitasahau nenosiri?
Hakuna njia ya kurejesha — ufichaji ni halisi, hivyo nenosiri lililosahaulika linamaanisha faili haiwezi kufunguliwa na mtu yeyote, sisi tukiwemo. Lihifadhi mahali salama.
Ni ufichaji gani unaotumika hapa?
AES-256, kiwango cha sasa cha ufichaji wa PDF, kupitia injini maarufu ya chanzo huria ya qpdf inayofanya kazi kwenye kivinjari chako.
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.
