How to password-protect PDF files on your smartphone
What's the story
Securing your PDF files with a password on your smartphone is a pretty simple task but one that ensures the privacy of your documents. Be it dealing with sensitive information or just keeping personal files safe, password protection is an important tool. Here's a guide to easy ways to protect your PDFs using different apps and features on most smartphones.
Native apps
Using built-in features
Many smartphones also come with built-in apps to add passwords to PDF files. For example, some devices have file management apps with security features. By opening the PDF in these native apps, you can often find an option under settings or tools to set a password. This method is pretty convenient as it doesn't require downloading additional software.
External apps
Third-party applications
There are plenty of third-party apps, both for Android and iOS, that provide strong security for PDFs. These apps usually offer easy-to-use interfaces where you can directly upload your document and define a password. Some popular choices may give free basic services, while others can charge a price for advanced capabilities.
Web tools
Online services
Similarly, online services offer another way to password-protect PDFs right from your phone's browser. These web-based tools let you upload the file, set a password of your choice, and download the protected version back on your device. Though convenient, make sure that the service you are using is reputable and secure.
Secure storage
Cloud storage options
Cloud storage services usually come with options for encrypting files before uploading them. By utilizing the built-in encryption tools of these services, you can add an additional layer of protection by putting passwords on your PDFs before uploading them to cloud. This way, even if somebody accesses your cloud account, they won't be able to open protected documents without the correct password.
