Some documents are not meant to be modified. They are created only for viewing purposes and their authors do not want anyone to tamper with them.
Such documents could be legal agreements, receipts, job and school applications, invoices, certificates, or any creative work (like a photo or illustration) that the author wants to protect from commercial use by other people.
There is no type of document format that is protected by default. PDFs, for example, are not editable, but there are many free conversion tools that can quickly convert them into editable formats. So, in order to protect their PDF files, users need software such as the PDF Converter Elite 3 that can secure sensitive documents in 3 different ways: by password-protecting, by adding watermark text, or by adding watermark images.
1. Create secure PDFs
PCE 3 helps you create secure PDF by password-protecting your document. This option allows you to choose who can open and who can edit your files. First open the PDF by clicking on the Open button.
Click on the Create button and then choose Set password from the drop-down menu.
In a box that appears select your security options. You can set a user password for opening a document, a master password for editing a document, and an encryption level.
You can also prevent people from printing, copying and pasting, commenting and modifying your document.
Advanced permissions for 128-encryption only include disallowing printing in low resolution, screen reading, etc.
After you fill in the Set Password box, click OK. You’ll receive a notification that the password was set successfully.
2. Watermark images
There are other ways to prevent people from using your document. Watermarking is a fine, easy solution for people who don’t want their work to be used by others. It is highly unlikely someone will sell or post on their website a photo that has your logo in the background.
Watermarking a document using images in PCE 3 is as easy as setting a password. Open the PDF file you want to watermark and click on Watermark image on the menu bar.
Alternately, you can click on the Edit button and choose “Watermark Image” from the drop-down menu.
The dynamic sidebar will appear with the following options:
Browse through your gallery of images and choose the one you wish to stamp on your PDF document. You also have a number of text, image sizing and stamp position options to set. Note the Placement option where you can set your image as an underlay or overlay watermark.
Click on the green Watermark image button and your watermark is placed.
3) Watermark text
Stamping a PDF document with text is another subtle way to prevent others from using it. The procedure is practically the same as in adding watermark images.
Open a PDF file and choose Watermark text from the menu bar.
In the Text to stamp box in the dynamic sidebar type in the text you want to use as your document watermark:
Fill in text, font selection and stamp position options and click on the green Watermark text button.
After viewing your document, you can always go back and modify your watermark until it looks how you want it.
Aside from protecting PDF files, the PCE 3 provides many more advanced features that can help users manage their PDF files and create stylish and secure documents.
