Three steps. That's it.
Password-protect your PowerPoint in three easy steps.
Upload File
Drag & drop your .pptx or .ppt file or click to browse. No PowerPoint license required.
Set Your Password
Enter a strong password. Your file will be encrypted with AES-256 — the same standard used by banks.
Download
Your password-protected PowerPoint file is ready. Share it knowing only authorized people can open it.
Built for accuracy, speed & security
Familiar with 100% Microsoft PowerPoint Fidelity
Our password protection is fully compatible with Microsoft PowerPoint, Google Slides, and LibreOffice. The protected file can be opened on any device with the correct password.
Keeps all Slides, Styles and Layouts
Password protection only adds encryption to your file — all slide content, fonts, layouts, images, and animations remain completely untouched.
FREE & No Sign-up Required
Our PowerPoint password tool is 100% free with no account required. Upload your file, set a password, and download the protected version instantly.
Secure Online Processing
Your files are encrypted with AES-256 during processing and automatically deleted after password protection. We never store or share your presentations.
