What encryption is used for the password?

We use AES-256 encryption, the industry standard for banks, governments, and security professionals worldwide. Only someone who knows the password can open your presentation.

Will my presentation content be changed?

No. Password protection only adds encryption to the file. All slide content, fonts, layouts, images, and animations remain untouched.

What happens if I forget the password?

If you forget your password, you can't recover it. We designed it that way to keep your file secure, so store your password somewhere safe.

Is the protected file compatible with PowerPoint?

Yes. The protected file is a standard .pptx file. You can open it in Microsoft PowerPoint, Google Slides (limited), and LibreOffice Impress with the correct password.

Yes, our PowerPoint password tool is free, with no sign-up required.
