Step 2: Add Text to Your PDF

When the file is uploaded, you’ll get to the dashboard, where you’ll be able to familiarize yourself with the whole set of our instruments. Firstly, let’s figure out how to add text to your PDF document. There are two ways to do it:

2.1. If the document already has a field for filling in, simply click on one of them and start writing.

2.2. If there are no fields to fill in, look for the "Add Text" tool on the upper dashboard. Click on it, then place the cursor in a place that you’d like to fill with text.

The text box is easily dragged across the document so that you wouldn’t need to be too precise on your first try. Everything about your text can be changed, including the font, size, format, and even color.

Step 3. Add Dates to a PDF

With the “Date” tool, you’re free to assign the document to today’s date or any other date of your choice. Just as with the regular text, there are two ways of entering the date.

3.1. If your document contains the date field, simply click on it and choose the one you need.

3.2. If there is no date field in your document, choose the “Add Date” tool in your dashboard and place the date field where needed. Today’s date will appear automatically. If you require another date, simply correct it.

4.1. If there are special fields for marks in your document, simply click on them.

4.2. If there are no special fields, click on the "Insert" instrument and choose one of the marks available on the dashboard and place it where you need. You can also create your custom mark by choosing the "Draw" tool.

Step 5: Add images to PDF

Besides the most used instruments, there are many additional options that are just as great. For example, you can add images to your document. As always, there are two ways for it: 

5.1. If the document already contains the required fields for images click on one of them.

5.2. If there are no ready-made picture fields, click on the “Insert” button, choose an "Add Image" tool and add your picture where needed.

How To Quickly Modify Your PDF

There are times when you are in harry and need to do some last minute changes to your documents. In these cases, an online PDF editor really comes in handy, because you can modify a PDF even with your phone. Here are the most popular features that you could use to edit your form after filling it out:

Highlight, whiteout, and blackout

Highlight and blackout instruments are used for quick transformations. The ‘Highlight’ tool is transparent and simply lets you mark parts of the text with bright lines without eliminating it. The “Blackout’ tool” paints it all black, while “Whiteout” tool simply wipes the chosen text out.

To highlight any part of the text, click on the “Highlight” button on the dashboard and find the part of the text you want to emphasize.

To hide the text, use “Blackout” or “Whiteout” instruments.

Switching between the pages

To make document navigation easier, we installed a ‘Pages’ box into our PDF editor. It lets you switch between the pages of the file by clicking on their previews. This tool also lets you add extra pages or change their order in the final version of the document. If you want to learn how to change page order, read our manual.

Adding editable fields

Another superb function is “Add Fields”: it can transform some outdated PDF form into the very document you need. This tool provides you with a bunch of unique functions, such as creating extra fields with text, date or any other type of data to customize your document. The signing option is available here as well. And keep in mind that you can not just sign your files, but also add your initials.

To add a field for editing, click on the “Add Fields” button that’ll let us see the new dashboard for this specific field.

There’s a set of instruments available. If you want to go through them step by step, read our editing guide.

Ready? Save

When everything is ready, just click on the ‘Done’ button in the upper right corner of the PDFLiner editor. It’ll take less than a minute for it to save all the changes in your document and place it in "My Documents" folder.
