Those who receive locked PDFs by e-mail or by downloading them from the Internet know that they aren’t so easy to unlock.

In most cases, this is difficult without the help of special software. If it’s pre-installed on your device, there usually isn’t anything to worry about - but you can’t always download such services both on your computer and smartphone.

Luckily this option is available online. Our service provides you with an easy-to-unlock option, that can provide you with exactly what you need. This solution can work on any internet-connected device and can operate on any web browser.

Just follow the steps given below:

The starting page contains the drag and drop box. This is for when you’re adding a file from your desktop computer or laptop. Also, there’s the opportunity to upload the PDF with the “Choose file” button. In addition to traditional methods, the sample can also be imported from any cloud service that you work with. Just select the upload method you prefer and your file will be ready in a few seconds. Then, the password insert interface will appear:

3 Unlock Your Document

 The next step is unlocking the file. First of all, select the desired language and make sure the “Caps Lock” button is off. The provided password may be long, so you may want to copy and paste it instead of typing it in. This is how a page with a typed password, ready for unlocking, looks like:
