Is this PDF corruptor tool completely free to use?

Yes, absolutely. Our corrupt PDF online tool is 100% free to use. There are no hidden costs, subscriptions, or limitations on generating test files.

How does the PDF corruption work?

Our tool modifies specific bytes within the PDF file structure based on the level you choose (Light, Medium, or Strong). Consequently, this simulates real-world file damage without affecting your original document.
