Minimum requirements for end user?

What are the minimum requirements (in terms of browser/device or specific HTML5 feature support needed) for the end user of H5P content and does it vary by content type? I couldn't find this anywhere in the documentation. 

For example, I've found that most (if not all) of the H5P content types do not work on a first-generation iPad using Safari. It would be helpful to know what the minimum requirements are so that we can inform our users.

Yes, it varies by content type. We probably should add this to the content type pages. We (Joubel) tests all the content types we create with:

  1. Chrome
  2. Firefox
  3. Safari
  4. IE11
  5. IE10
  6. IE9
  7. Chrome for iPad
  8. Safari for iPad
  9. Safari for iPhone
  10. Various Android devices

We use the newest versions of the browsers and platforms mentioned above

Is Explorer 8 supported for course presentation and interactive video?

falcon's picture

no, it is possible to add support for it, but currently H5P does not work for IE8.


I have tested all the content types in the latest version of Safari for Ipad and Iphone. I' ve found that only a little selection of modules work: timeline, image hotspots and flashcards.

I'm interested to run Drag&Drop, Memory game,  Quiz (Question set) modules on Safari for Ipad and Iphone. Also Interactive video would be great to use it at least on Ipad, as it permits to reproduce an embebed video (for Iphone I know it is not possible because it forces to use the native video player).


1. Is there any solution to use Drag&Drop, Memory game,  Quiz (Question set)  on Safari for Ipad and Iphone?

2. Is there anry solution to use Interactive video on Safario for Ipads?

Many thanks

Thank you for the feedback. Have started to investigate this, all H5P content types are tested with both iPhone and iPads so it is strange that they're not working for you. Are you testing on content created on your own site? Do you have the latest version of IOS?

  1. Drag and Drop and Memory Game works fine on my iPhone. What is it that isn't working for you? Question Set however does not. The drag and drop on question 2 goes wide and I'm stuck on question 2 (!!!) We will fix this today or Monday and release a hotfix release.
  2. Yes, I tested the Interactive Video example now on my iPad and it works fine. What is it that isn't working for you?

Hope you're able to get back to me here asap. H5P shall work perfectly on mobile devices.

The version available on should be updated with a fix for resizing of Drag and Drop inside Quiz (Question Set) now.

Hi Falcon,

Thank you so much for your quick answer. After your confirmation that worked for you on Iphone and Ipad we have done a new series of test on our devices.

The problem for us was that the whole modules mentioned didn't show at all on the page. Tested on your page and in a Wordpress website with Twenty Fifteen theme.

However we've found the problem: some modules do not work in private browsing mode.

When swichted to regular browsing almost everything works perfectly.

So this it the result of our lasts test:

1. On private browsing on Ipad or Iphone the following modules do NOT show:

  • Accordion
  • Collage
  • Course presentation
  • Drag and drop
  • Drag te words
  • Fill in the blanks
  • Find the hostspot
  • Guess the answer
  • Impresive presentation (ALPHA)
  • Interactive video 
  • Mark the words
  • Memory game
  • Multiple choice
  • Quiz (Question set)
  • Single choice set
  • Summary

2. On regular browsing on Ipad and Iphone the following modules do NOT show/work:

  • Interactive video : only in Iphone because of native video behaviour
  • Impresive presentation (ALPHA): in Iphone does not show, in Ipad shows and works ok
  • Quiz (Question set): it shows in Ipad and Iphone but the Drag&drop question does not adjust fine to the screen size, especially on Iphone

I hope this info helps you. It would be great if you could fix the problem with the private browsing as a lot of user use this feature. We would love to use your system in our site, but we need to be sure it will work in the most common devices/browsers and use contexts.

Thank you for the amazing job you're doing!

This issue should be fixed now. Thanks again for reporting it!

Hi all,

I've just found the same issue with the latest version of H5P. Currently using 1.7.3 in wordpress, and Interactive Video doesn't seem to work in an IPad.

You can check the issue at:

Thank you so much for your support.
