Why Draw on a PDF?

There are a million use cases where you might need to write on a PDF so let's take a look at some of them so you can see how valuable a tool like Markup Hero is.

Use Case #1 — Filling out forms for work or school

Teachers and business people often use PDF forms or worksheets for various use cases. Adding text, arrows, boxes and other annotations to these PDF documents can be a fast and easy way to fill them out, give feedback or comments.

Use Case #2 — Adding comments to an article or document

Professionals, students and freelancers frequently need to add comments to articles or other types of PDF documents. This can be done easily by writing on PDF's using text tools as well as markup with other annotations like colors or lines.

Use Case #3 — Hiding content from private files

Sometimes you have a PDF with sensitive data you want to hide from people you share the document with. This can be done easily with a blur or blockout tool by covering up the secure information permanently so nobody can see or inspect the document structure to get past the block.

Use Case #4 — Highlighting important information

Often you may have a PDF document, article, website or other file and you want to highlight specific lines, words or paragraphs. This can be done with a PDF highlighter tool very easily.

Why Other PDF Editors Don't Work

There are many options to draw on PDF's, from the original Adobe Acrobat to a bunch of 3rd party tools and PDF software you'll find on Google. In some cases, where you need to do really advanced editing of text and formatting of the original PDF file, these tools might be a good option. But if you're just looking for a quick way to draw on a PDF, add annotations to PDF's or write on PDF's, then the solution outlined in this article is going to work better.

Additionally, PDF's can be rather large in file size. That means it can be slow to open and edit while the original PDF re-renders. This is a common issue with Acrobat for example. But our solution converts the PDF into images which are smaller and won't bog down your computer. This makes adding markup to your PDF way smoother and allows you to annotate 100+ page PDF's with ease.
