AltoProtectPDF: Secure PDF Files for Free

The transfer of sensitive or personal information via messengers of e-mail is not always as secure as it's supposed to be.

Locking file with a complicated password that only you and the receiver will know is usually ideal.

Just click on the extension, add it to the document and lock it.

• Easy to work with. The service locks your files in just a few clicks
• Add documents not only from the device’s internal storage, but also directly from Google Drive
• The document quality, as well as the internal formatting of data, remains untouched
• No payments. The function is available right after installation for free
