How to Publish Free Interactive Maps with qgis2web and GitHub Pages

How to Publish Free Interactive Maps with qgis2web and GitHub Pages makes turning a static geographic information system (GIS) project into a live, shareable web application effortless without writing custom JavaScript from scratch. Today, GIS professionals, urban planners, and students can bridge desktop GIS and modern web publishing entirely for free using two powerful open-source tools: qgis2web and GitHub Pages.

By using the qgis2web GitHub Pages free web map workflow, you can Export QGIS to Leaflet, Host web GIS map free, and showcase rich Interactive map web publishing portfolios without spending a dime. Following this comprehensive tutorial on How to Publish Free Interactive Maps with qgis2web and GitHub Pages ensures you can share your work instantly.

Introduction: How to Publish Free Interactive Maps with qgis2web and GitHub Pages

If you have ever built a map in QGIS, you know how powerful its styling, labeling, and cartographic design tools are. However, sharing that map with stakeholders, clients, or the general public usually meant exporting static PDF layouts or image files that lack interactivity.

The qgis2web plugin solves this by translating your QGIS layers, symbology, and attribute tables directly into web-ready code (HTML, CSS, and JavaScript via Leaflet or OpenLayers). Combined with GitHub Pages, which provides free static web hosting straight from a code repository, you get a zero-cost infrastructure to deploy professional, browser-based maps accessible anywhere in the world.

Step 1: Preparing Your Map in QGIS

Before exporting your project, clean up your QGIS workspace to ensure the web map renders smoothly and cleanly in a browser.

Clean Layer Names: Rename your layers in the Layers panel. The names you use here will automatically populate your web map’s layer switcher list (avoid special characters and spaces if possible, using underscores or clean title case instead).
Configure Pop-up Attributes: By default, clicking a feature in your web map will display its attribute data. Open your vector layer Properties > Fields, and set unnecessary ID fields to “Hidden” or configure friendly aliases so your users see clean, readable labels instead of raw database columns.
Optimize Symbology & CRS: Keep complex vector geometries reasonably simplified to reduce load times. Ensure your project is set to a web-friendly Coordinate Reference System (CRS) such as EPSG:3857 (WGS 84 / Pseudo-Mercator), which is standard for web mapping libraries like Leaflet.

Step 2: Configuring the qgis2web Plugin

The qgis2web plugin converts your project canvas into a fully functional web map interface.

Install the Plugin: If you haven’t already, open QGIS and go to Plugins > Manage and Install Plugins. Search for qgis2web and click Install Plugin.
Open the Exporter: Navigate to Web > qgis2web > Create web map. A configuration panel will dock on the right side of your screen.
Choose Your Mapping Library:
- Under the exporter options, choose between Leaflet (recommended for lightweight, mobile-friendly maps with extensive plugin ecosystems) and OpenLayers (ideal for heavy enterprise datasets or advanced spatial operations).
Configure Interactive Widgets:
- Layers list: Check this to let users toggle individual vector and raster layers on or off.
- Popups: Select whether feature information appears on Hover or Click. “Click” is usually best for touchscreens and detailed data inspection.
- Search bar: Enable the search widget to let users look up features by attribute fields (e.g., searching for a city name or parcel ID).
- Appearance: Set your map canvas dimensions, add a scale bar, and choose a clean web basemap (such as OpenStreetMap or CartoDB Positron) to sit underneath your custom layers.
Preview the map directly within the dialog box to check your styling and layer behavior before exporting.

Step 3: Exporting the Web Map Package

Once you are satisfied with the preview:

Click the Export button at the bottom of the qgis2web panel.
Designate an empty folder on your local computer to save the export package.
The plugin will generate a self-contained directory containing:
- An index.html file (your main application entry point).
- A css/ folder with stylesheet files.
- A js/ folder housing the Leaflet/OpenLayers scripts and data files (often stored as GeoJSON or JS arrays).
- A images/ or layers/ folder containing your custom markers and spatial data.
Double-click the index.html file to test it locally in your web browser and confirm everything functions correctly.

Step 4: Hosting on GitHub Pages

With your local web map package ready, it’s time to publish it to the live web using GitHub.

1.Create a Free GitHub Repository:Set up your remote storage container.

Log into your GitHub account, click the + icon in the top right corner, and select New repository. Name your repository (e.g., qgis-web-portfolio), set it to Public (required for free GitHub Pages hosting), check Add a README file, and click Create repository.

2.Upload Your Map Files:Add your qgis2web output to the repository.

Inside your new repository page, click the Add file dropdown and select Upload files. Drag and drop all contents of your exported qgis2web folder (make sure index.html is in the root directory of the upload, not nested inside an extra folder). Click Commit changes.

3.Enable GitHub Pages:Turn your repository into a live website.

Go to your repository’s Settings tab. In the left sidebar, click on Pages. Under the Build and deployment section, set the Branch dropdown from None to main (or master), leave the folder as / (root), and click Save.

Step 5: Testing Your Live Public URL

After a brief moment, GitHub will build and deploy your site. Refresh the GitHub Pages settings page, and you will see a banner displaying your live web link:

https://<your-username>.github.io/<repository-name>/

Click the link to view your fully interactive, hosted web map live on the internet! You can now share this URL with peers, clients, or embed it into your professional portfolio.

Conclusion & Next Steps for Student Portfolios

Publishing web maps doesn’t require a background in full-stack web development. By mastering the workflow of styling data in QGIS, exporting via qgis2web, and deploying via GitHub Pages, you can rapidly prototype and broadcast geospatial stories.

To take your mapping portfolio further, try editing the generated index.html file to customize the header title, tweak CSS styles, or integrate external widgets like custom legends and charts. Ultimately, mastering How to Publish Free Interactive Maps with qgis2web and GitHub Pages is an essential skill for modern geospatial portfolios.

Frequently Asked Questions

How do I update my map after publishing it?
If you need to make changes to your layers or styling, simply re-run the qgis2web export in QGIS to overwrite your local files. Then, go to your GitHub repository, upload the updated files, and commit the changes. GitHub Pages will automatically refresh your live site within a few minutes.

Is it completely free to learn How to Publish Free Interactive Maps with qgis2web and GitHub Pages?
Yes! Both QGIS and GitHub offer free tiers and open-source licenses, allowing you to build, host, and share unlimited web maps for your professional portfolio without any subscription costs or hidden hosting fees.

Can I customize the code after exporting?
Absolutely. Once you export your project package, you can open the generated `index.html` file or look inside the `css/` and `js/` folders using any text editor to fine-tune your popup styles, add custom headers, or integrate external widgets.
