How to Annotate Scanned PDF

1. Standard text boxes — included in a document where it is convenient and suitable;

2. Sticky notes — attached over the content of a document

With pdfFiller functionality, not only can you fill out and edit PDFs and other types of text documents, but you can also annotate scanned PDFs and guide recipients through a document’s content. Alternatively, notes are helpful in terms of your own revisions to a document. pdfFiller has two types of note tools: To comment using a text box, select Text Box in the toolbar and click where you'd like to place the box in the document. To resize a text box, drag its corners or edges. To change the color of its border, click the color icon that says Box in the formatting toolbar and select the color that you want. To change the color of the box itself, click Background and choose the color:

To enter text in a box, click inside and start typing. When you annotate a scanned PDF file, you can change the font type of the note. Simply click the box with the current font name in the formatting toolbar and choose from the dropdown menu. You can change the font size by clicking the number next to the font and selecting from the dropdown list. To underline your text, make it bold or italicized, use the U, B, and I icons. To change the text color, click the color box on the right of the font tools and select the color you want:

I AM NEW AND LEARNING BUT SO FAR IT IS GREAT. EVEN IF I ONLY PRINT A FEW FORMS A MONTH THE SMALL PRICE IS WORTH THE CLEANESS OF THE FORM. I HAVE BEEN HAND WRITING THEM AND USING WHITE OUT.. I AM GLAD FOR THE SHARPNESS OF THIS AND EASY TO FIND FORMS ..

What do you like best?
The site is intuitive and everything is organized in a no fuss manner. Scanning in documents and making changes is easy.
What do you dislike?
The printing of documents can be tricky sometimes. Most of the time I save as a PDF and open with Adobe.
Recommendations to others considering the product:
Have the basic Adobe software as well. It makes printing documents, in the proper size, much easier.
What problems are you solving with the product? What benefits have you realized?
We have many documents that have to be changed constantly. Tax Exemption Forms, Charts and Invoices. This makes it very easy.

The most common reason that you can't highlight PDF documents is because the document doesn't actually contain any real text. Instead, it contains scanned text, which is essentially an image of the text. In this case, you won't be able to highlight, underline, strikethrough, or edit this text in any way.
Therefore, to enable highlighting in PDF document it is necessary to bypass Permissions Password for commenting. Once, the security is removed from the PDF file users can easily select and highlight secured PDF document.
