With GeoGebra 4.2 we have introduced pure HTML5 GeoGebra documents. This way GeoGebra applets start even faster than before, and this technology provides availability of GeoGebra for smartphone users as well since Java is no longer a prerequisite. Such documents currently have only a limited set of commands (e.g. spreadsheets do not work yet), and they have no menu driven graphical user interface, but have otherwise the same features as usual GeoGebra documents. The main advantage is GeoGebra runs on a wider set of hardware at a more comfortable speed, but to harness all the possibilities, one should always use the latest web browsers. In short, we call this technology GeoGebraWeb, and the documents created by this method are called GeoGebraWeb documents.

There are two types of GeoGebraWeb documents: online and offline. Online documents are usually hosted by the official GeoGebra servers, primarily by GeoGebra; and offline documents are usually put on intranet servers by members of the GeoGebra community, or even on the end users' own machine.

We suggest using online documents everywhere! GeoGebra automatically detects the users' web browser and decides if it is running on a smartphone, and serves the document in GeoGebraWeb format. Hence we strongly suggest to upload all your documents to GeoGebraWeb if you want to publish teaching materials. This has a great advantage: GeoGebra will show always the latest GeoGebraWeb document when a user wants to visit it on her smartphone. In some cases, however, GeoGebra cannot identify the end user's machine correctly: in such cases we recommend to add the &mobile=true setting to the end of the document URL.

Offline documents

In some situations it is useful to have offline GeoGebraWeb documents available. For example, if internet is not available during a classroom teaching, or during a travel without good enough internet connection.

Since version, offline GeoGebraWeb documents can also be created in GeoGebra by following these steps: In File menu, go to Export -> Dynamic worksheet as webpage (html), and click the "Export as Webpage" tab, then select the "Advanced" tab and check for the following options in the "Files" settings:

  • Export to HTML5 only
  • Allow offline use

Then press "Export". Now GeoGebra will automatically download the required set of files and copy them into the appropriate directory. Please expect approximately 40 MB of data for an offline GeoGebraWeb document. You can simply copy all the created files for this export to another directory or another machine, and use them.

How GeoGebraWeb works

GeoGebraWeb consists of a set of HTML files which will be downloaded from the GeoGebra Developer Site by GeoGebra on a user initiated export. The files are packaged in a .zip archive, and can be downloaded manually as well. However, these files are not intended for end users. For those who are still interested in the internal details, and want to tweak the HTML files, we provide some additional information here.

The latest version of GeoGebraWeb can be downloaded from http://dev.geogebra.org/download/web/GeoGebraWeb-latest.zip.
