Part 3. Cons of Using PDF AI Extensions

Even though we have discussed the many different PDF AI extensions, sometimes it can be bad to use a browser extension. One of the biggest problems is that web browser extensions often do not work on mobile devices. You also cannot use browser extensions when you're offline, so it can be difficult or impossible to access your PDFs when you don't have access to the internet. Web browser extensions can also sometimes be very limited - they don't offer many customization options for users, and they can often slow down the speed of your web browser. For these reasons, sometimes it's best to use a desktop tool for working with PDFs.
