How to Use Spell Check with PDF

It can be extremely awkward when someone points out spelling errors in documents you have created. Not all of us have access to professional editors, or even someone to double-check your work. Knowing how to use spell check for your PDFs will help make sure you catch any unwanted typos.

Even the best spellers can benefit from a tool that gives your document one last look before you finalize it. A good spell check tool will identify any errors and then provide you with the correct spelling for the word. Most importantly, you’ll have the option to ignore it if you want to use customized spelling in your PDF file.

Knowing how to use spell check in applications like Microsoft Word is common enough. It’s been automatically available as far back as we can remember. A good PDF editor, like Soda PDF, will let you replicate that familiar functionally when working with PDF documents.

Using Soda PDF’s spell check tool, you will see a familiar red squiggle line appear under any word that has a mistake.
