How To Sign PDF
PDFLiner is a set of top editing tools for your PDF files integrated into one online service. With them, you can easily customize your documents on the go, keep them secured and organize your workflow and your interactions with other users.
The online signature tool is, probably, the most used instrument out of our online editing accessories. Let’s learn its multiple functions and how to work with them.

There are tree ways of signing your PDF file.
1. If you’ve used our service before, you must remember the ‘Sign’ button on your dashboard. It has an ink pen icon and is situated in the upper left. Click on it!
Step 1. Click on the ‘Sign Field’ button.

Step 2. Click on the ‘Add New Signature’ button.

Step 3. Choose how you want to add your signature.

Now You Have Your Signed PDF👍
Keep in mind that PDFLiner not just lets you sign any document online and save it momentarily. You can also make your own files with added signature fields and share them with other users so that they could fill and sign them.
To organize your workflow, you need to be logged in to the PDFLiner system and have the person you want to share your documents with logged in, as well. If they are not familiar with the PDFLiner service yet, you can use third-party products for file-sharing.

When you’re a student, you deal with PDFs a lot… Newsletters, various worksheets, official forms you need to fill in and sign, etc… To me, filling out a PDF form used to be among the trickiest and most time-consuming things ever.
