Put a working index.html at the top level of the zip (not inside a subfolder), use relative paths for all assets, include every file the game needs to run offline from that folder, and test it by serving the folder locally before you upload it to any platform.<\/strong><\/p>\n

Structure the zip so that index.html<\/code> sits at the root, not inside a subfolder – most web servers and game portals load index.html<\/code> as the default file, and if it’s nested one level down the platform’s loader often fails to find it. Every asset the game needs (JS, WASM, images, audio, JSON data) should be inside that same zip, referenced with relative paths, so the game runs the same whether it’s hosted at a domain root or under a subpath.<\/p>\n

If you publish through Playgama, the open-source Playgama Bridge SDK adapts one HTML5 build to 25+ platforms. <\/p>\n

Before zipping, serve the build folder from a local web server and load it in a browser exactly as a platform would – opening index.html<\/code> directly via file:\/\/<\/code> often breaks WebGL and fetch calls. Check the browser console for 404s on assets, confirm audio and save data (Web Storage) work, and confirm the canvas resizes correctly. Unity WebGL and Godot web exports both produce a folder with an HTML entry point plus JS\/WASM\/data files; zip that whole folder’s contents, not the folder itself, so the paths inside the archive are flat.<\/p>\n

Where can you upload the finished zip?<\/h2>\n
