Transparency of shapes and images

I like the tool. The thing I really miss is transparency. With that you could do a lot of cool things with the layers - like merge text into walls in a photo etc. Is this something that is being under consideration?

Hi Tobias,

if you use PNG or SWF graphics, transparent image backgrounds are possible already. And text boxes have transparent background by default. Ergo, you can both merge text onto an image background, or let text “shine through” transparent sections of an image.

For more advanced photo editing, you’ll have to use 3rd-party tools though.

Kind regards,


I feel that transparency would be a pretty basic tool to implement and would have a lot of uses. Is there really zero consideration about adding it to the toolset? Having to convert to PNG, open in an editing program, and convert to alpha seems pretty unwieldy, especially for multiple images.

For me the issue is variable transparency; i.e. I don’t want visible or not visible. I would like the ability to have something like a colored box that is semi-transparent fade-in over a picture so that the text that I fade-in is more visible against the picture in the background.

Is it still possible in the new version?

We should be given the ability to give a level of transparence to any image and the ability to add it as an animation that as the image is being brought out of transparency into full bold upfront view.

After making your shape, open the CSS editor and  scroll down to the “shape” portion of the coding and change the gradEndAlpha and gradStartAlpha values. This will change the opacity.

Hello Lindsey Heale,

thanks for sharing - for those who want to see more on this please see the CSS help page



Don’t forget that (if you haven’t already) you can upgrade your license to get more features (own logo, privacy and more space for your Prezis -

Shapes can be made more or less transparent, but images too? Where can you change the transparency - I could not find the way to change it? Is it already possible or are you still working on the feature?

Regards Annette

Like Annette, I am looking for the ability to set a transparent color in an image. This can be done in Powerpoint 2010… when will it be available in Prezi. Or is it, and I need help finding it?

Thanks for the update, and for the link; very helpful. I hope that setting a transparent color is on a development list somewhere, because it would be a very helpful feature; it’s something we use extensively in PPT (one of the few features we appreciate in that solution). 

It would be extremely useful to be given the ability to set a level of transparency to any image or shape, just like size or coloreffects. 

An additional ability to use the opacity/transparency of that image or shape as an animation tool during the presentation would add tons of great possibilities e.g. fading in and out.

PNGs create transparency in one of two ways. One of these methods employs the same approach used by GIFs, with a single color defined as transparent, and the other is to set an alpha channel. One of the advantages of PNG single-color transparency is that it doesn’t remove a color from the available palette. However, the alpha channel is a much smoother method, as it is far better at blending colors, and allows you to select different levels of transparency in specific regions. The transparent areas of the PNG will blend and adjust naturally to whatever is behind the image when the background of the page isn’t a solid white or black color.
