We think that it’s really important to make PowerPoint presentations accessible. And that means: writing alt-text for all the images.
If you’ve ever clicked, clicked, clicked through a long set of slides, checking the alt-text on each image one by one: you’ll love this app. Especially as it’s free to use.
We’d also like to thank Peter Flynn for his help in cracking the .pptx format.
The app reports on what it finds on each slide
The app opens with a single button to upload a file.
It only understands .pptx format. if you try anything else, it won’t work.
There’s a short pause, and then you get a report with what it finds on each slide.
I gave it a deck with just two slides: both of them look just like the one in the image above. The first slide is typical of the sort of thing that flummoxes an accessibility checker: there’s alt-text on the slide, but it’s useless for anyone reading with a screen reader. The second slide also has alt-text, but this one has a description of the image. Here’s the example report on the two slides.
Request for extra help
This app is a completely volunteer effort. If you spot some improvements and would like to make them, please get in touch: extra help would be welcome.
