How to host an HTML file online
Turn a local HTML file into a shareable website. Import your .html file or paste its code, publish with GemiGo, and check the live link. No Git repository needed.
How do I turn an HTML file into a URL?
Open Publish an app and choose HTML. Use Import .html file to load your local file, or paste its HTML code. Sign in when asked, publish, then open and share the website URL after deployment succeeds. You do not need a GitHub repository for this publishing path.
1. Import your HTML file or paste its code
Choose Import .html file and select your .html file. Its contents appear in the HTML input so you can review or edit them before publishing. You can also paste the code directly. Review external scripts and API calls; keep private keys out of browser code.
2. Publish and check the result
Start publishing and follow the deployment status. Once it succeeds, open the resulting website URL in another browser tab and check the app’s controls, images and mobile layout. A successful upload is not proof that every external dependency works.
3. Share or update the app
Share the resulting link with your audience. To publish a change, open the app in your dashboard and use its project settings to redeploy. Public discovery is a separate setting; an unlisted app can still be opened by anyone with its deployed URL.
Can the HTML file include CSS, JavaScript and images?
CSS in a style tag and JavaScript in a script tag travel with a self-contained HTML file. Separate local images, stylesheets and scripts are not imported with it; package those files together as a ZIP. Local filesystem paths do not become public URLs. Check the live page and any external APIs before sharing.
Try it: a small addition activity
This example was written by GemiGo. It runs offline, checks answers and generates another question without external APIs. Try it in your browser, then download and publish it through the matching input. It demonstrates the publishing workflow; it does not claim a learning outcome.
How do I import this HTML file?
Download addition.html, open the HTML publishing input, choose Import .html file and select that file. Its code appears in the input. You can also open it in a text editor and paste all of its code. Styles and scripts are already inside this file. After publishing, enter 5 and press Check: the first question should say Correct. New question should change the exercise.
Images, styles or scripts do not load?
Open the asset URL directly. A 404 usually means the archive path or filename does not match the reference. C:\, /Users/ and file:// are local filesystem paths, not published image addresses. If assets load but the page stays blank, inspect the browser console: an external API may reject cross-origin requests or require sign-in. Remove private credentials before uploading.
What about React or Vite source code?
For a ready-built site, run your project’s build command locally and zip the output files—for example, put index.html and assets/ from inside dist/ at the archive root. For source publishing, include package.json, dependency declarations, source files and required configuration so a supported build can produce static output. If only deep links fail, check application routing and the asset base path.
