Office hacks: Protect copyright so that PPT can be seen but not changed

I wonder if you have encountered a similar situation: want to share a PPT presentation to others, but do not want to be changed, hoping to keep the original presentation; or the need to make the presentation part of the page or material can not be modified; or just want to see each other static version of the picture manuscript …… This article will share with you some so that PPT can see the “secret sauce” can not be changed.

Add Read-Only Permissions

Adding “read-only” permissions to a file is the most common protection method for PPT. You can add open files or change the password of a file as needed to protect the file when saving it.

After opening the file, click the “File” menu, select “Save” after the pop-up dialog box (Figure 1), click the “Tools” button to select “General Options”, and then in the “modify permissions password” to enter the password, enter and then confirm once, so that the next time you open the file, if you will be prompted to enter the password to modify the file, or select “read-only” to open the file. Read-only way to open the file, you can see that the presentation is normal, but want to copy or modify the material inside, is not possible.


There is a special case, the manuscript is handed to the other side, it is possible to modify, but must let the other side know that this is the final version we provide, modified after will not be responsible for any text, here you can mark the manuscript as the final version. Click the “File” menu, in the “Information” option, click “Protect Presentation” select “Mark as final “(Figure 2), so that if the other party has opened the file and modified it, then the final status icon marked will disappear, which indirectly means that it is not original.


Partial Prohibition of Modification

Compared to the more obvious method of prohibiting modification by setting a password, the PPT plug-in “Beautifier” ( is a bit softer, as it locks the objects on the page so that they cannot be moved or deleted.

After installing PPT Beautification Master, a “Beautification Master” tab will be added to PPT. Open a presentation, switch to the “Beautifier” tab, click the “Read Only” button to select “Lock”, and then enter the password (Figure 3), so that the current presentation pictures, text, graphics (except lines) can not be selected, and in the lock after adding the content, but also no impact, as usual, you can edit and modify. Through the beautification master will be important content locked, secondary content added later, thus meeting the need to partially prohibit the modification.


Specific objects are forbidden to be changed

The core images or text in some pages in PPT are not allowed to be modified, while other contents can be modified. With “Pocket Animation” (, a popular animation plug-in, you can lock some of the material in the page.

Open the presentation, switch to the “Pocket Animation” tab, first click the “About” button to select “Professional”, so that you can use the “Super Lock” function. Click the “Design” button to select “Super Unlock → Locking Options” pop-up dialog box (Figure 4), here you can choose which options to lock, such as, size, move, rotate, text editing, etc., in the “Original Protection “in the” select “use the default password,” and then enter a password behind their own, click “OK” button can be. Finally, select some material in the page, click the “Design” button to select “Super Unlock” under the “Object Lock”, so that the selected material can be locked. When the need to unlock, select the material select “object unlock”, according to the prompt to enter the password to unlock.


The master version “mask” rookie

Have seen the beginning and end of some PPT presentation, the use of the wonderful animation as the opening and closing credits, we want to copy over to use, but found that you can not copy, and in the “animation pane” but can not find any action, which makes many rookies very confused, the author often encountered similar situations in the early days. In fact, it is very simple to understand, the author is the opening and closing animations in the master version.


After opening the presentation, switch to the “View” tab, click the “Slide Master” button to open the master (Figure 5), where you can generally see the use of animation effects in the credits, copy directly to the PPT page can be used. If you want to use the animations in the master page, right-click on the page list on the left and select “Layout”, you can see the corresponding animation layout, select it and apply it to the current page.

Convert file format

In addition to the above-mentioned PPT protection methods that can be seen but not changed, there are some more “alternative” secrets, which can see the content of the PPT, but not the “original”. Such secrets are summarized in the conversion of PPT formats such as PDF, pictures and videos.


After opening the presentation, click the “File” button to select “Save As” pop-up dialog box (Figure 6), in the “Save as” type you can save the presentation as PDF, XPS document In “Save as” type, you can save the presentation as PDF, XPS document, or MP4 video, single JPG, PNG format picture, and PowerPoint projection file, etc.


In some websites selling PPT templates, we usually see that they put all the pages of the PPT together in one picture, using the PPT plug-in OneKeyTools (, you can directly jigsaw the selected pages. After opening the manuscript, press Ctrl+A in the list of pages on the left to select all pages, then switch to the OneKey tab, click the “OK Puzzle” button (Figure 7) and select “Guide Settings”, you can set the resolution of a single picture. Select “Quick Puzzle” to automatically export the selected page as a picture. Select “Free Puzzle” pop-up dialog box, you can set the width of the picture and the number of columns, as well as the background color, whether to set a large picture, etc., and finally click the “Puzzle” button to generate a puzzle.



If you want to make the presentation as much as possible to show the “original”, showing the dynamic effects, then as far as possible, the PPT exported to the use of “record slide show” video, so that you can show some of the details of the PPT as much as possible.

Switch to the “Slide Show” tab, click the “Record Slide Show” button and select “Record from the beginning” to open the recording interface (Figure 8), I am using PowerPoint2019, the interface is slightly different. Click the “Record” button, you can play the presentation as the audience, the end of the projection of all the presentation process will be recorded, and even to each page to add a synchronized explanation of the voiceover, the end of the recording back to the main interface.


Click “File” button to select “Export”, click “Create Video”, select “Use recorded timely and narration” (Figure 9), and finally click “Create Video” button to export as the closest to the actual presentation. “PowerPoint2019 can export 4K video now.
