How to Protect a PDF File

AltoPDF team

Jan 22 2020 / 11 min read

Those who share their documents via e-mail or various other electronic methods understand that not all information in those documents is meant to be accessible to everyone. That is why we need to have the option to safely share documents without the fear of having our information stolen or compromised.

With our online platform designed for editing PDFs, a template can be easily protected. To be fully sure that your document will not be opened by anyone (except the person you address it to), you are given the option to lock it with a secure password. What’s especially useful is that these platforms can be used with any internet-connected device and on any internet browser.

To successfully use this online platform, follow the recommendations given below:

1 Open the Web Platform

To lock your sample, you have to to open the website by inserting the address into the address field, or simply by inserting Alto Protect into your respective web browser. Click at the following link, and you will be redirected to the starting page. Its interface is quite simple and self-explanatory. There are no complicated toolkits or distracting advertisements.

The starting page will look like the following:

2 Upload your Document

To add your file, you need to drag and drop it into the upload box or browse for it in your device’s internal memory. Also, this service offers the possibility of adding the file from whatever cloud storage service you work with. Once your document is added, it will be ready to be locked in a few seconds.

3 Protect Your PDF With an Intricate Password

For this step, you should select a password that’s easy for you to remember, but difficult for others to guess. When choosing you password, take the following into account:

  • Make it longer than 8 characters;
  • Try not to use widely known phrases;
  • Do not use the same password that you use for another device/program;
  • Combine capitalized and lower-case letters with numerals and symbols (if possible).

Once you have selected a secure password for your PDF, insert it in the corresponding field and click on the “Protect File Now” button. The system will automatically detect whether your combination of letters and numerals is secure enough.

4 Download the Locked File

The locked document will be downloaded to your device or cloud storage once the process is completed. The system will automatically remove both the original and final versions of the sample in order to keep your information safe. If you want to repeat this operation with additional documents, click on “Start over again” or just reload the page.
