About Protect PowerPoint

Password protect PowerPoint decks that aren't meant for everyone: a pitch with this year's numbers, a product roadmap, a board presentation that goes out a day early. Upload the PPTX, type a password twice and download an encrypted copy that PowerPoint opens only after the password is entered. A deck too big to email can be shrunk with Compress PowerPoint first, then protected.

The deck is encrypted with AES-256, the method PowerPoint itself uses for Encrypt with Password, so the recipient needs nothing extra. Slides, notes, pictures and media are all inside the encrypted file. We use your password only while the task runs and delete it from our records afterwards. A lost password can't be recovered by anyone.

How to use Protect PowerPoint

  1. 1
    Upload the PPTX

    Click Choose file or drop your presentation on the page.

  2. 2
    Choose a password

    Type it in Set a password, then again in Repeat password.

  3. 3
    Click Protect PowerPoint

    The deck is encrypted in an isolated process. A PPTX that already has a password is refused.

  4. 4
    Send it on

    Download the copy ending in _protected.pptx and share the password separately, for example in a call.

Why use Cubfile for this

  • PowerPoint's own encryption

    AES-256 as used by PowerPoint on Windows and Mac, so no special viewer is needed.

  • Nothing readable without it

    Slides, speaker notes, pictures and embedded media are all encrypted.

  • No copy of your password

    It's deleted from our records the moment the task ends.

  • A new file for sharing

    The encrypted deck is saved as a separate _protected file, so your working copy stays open.

FAQ

Protect PowerPoint: questions and answers

Can I still present from a password-protected deck?
Yes. Enter the password when PowerPoint opens the file and everything works as usual, including animations, notes and Presenter View.
Can I password protect PowerPoint files in PPT format?
This tool takes PPTX only. Open an old PPT in PowerPoint or WPS, save it as PPTX, then upload it. For Word and Excel files, the matching password tools are in Word, Excel & PPT Tools.
Is it free to password protect a PowerPoint?
Yes. You can try 2 tasks without an account, and a free account gets 2 a day, for presentations up to 50 MB. VIP has no daily limit and handles decks up to 1 GB.
What if I forget the password?
The deck stays encrypted for good. There's no reset and we don't keep the password, so store it in a password manager.
Do you see my slides or password?
No. The file and password travel over HTTPS, the encryption runs in an isolated process, and the password is erased as soon as the task finishes. Files are deleted after an hour.
Share Protect PowerPoint with a friendIt runs in any browser, and they can try it without signing up.
