If you're looking to get rid of check marks in Adobe Acrobat, there are a few different ways you can go about it. One option is to use the built-in editing tools to remove the check mark from your document. To do this, open up your document in Adobe Acrobat and click on Edit > Checkmark. From here, you can simply select the check mark you want to remove and hit the Delete key on your keyboard.
Another way to remove check marks from Adobe Acrobat documents is by using third-party software. There are a number of different programs out there that can be used for this purpose, and they typically work by allowing you to select the check mark you want to remove and then clicking on a button to delete it. Some of these programs even come with additional features that let you edit other aspects of your PDF documents, so they're definitely worth checking out if you need more than just basic check mark removal capabilities.
No matter which method you use, removing check marks from Adobe Acrobat documents is relatively easy and shouldn't take more than a few minutes of your time.
