.html file (or a .zip of the whole project), set the app name and icon, and tap Build. Your files are packed inside the APK, so the app opens instantly and works offline. Use a ZIP whenever the page loads separate CSS, JS or image files.HTML to APK vs website to APK
The two sound alike but behave differently:
| HTML / ZIP to APK | Website (URL) to APK | |
|---|---|---|
| Where the content lives | Inside the APK | On your web server |
| Works offline | Yes, fully | Shows an offline screen |
| Update content | Rebuild the APK | Edit the website |
| Needs hosting | No | Yes |
| Best for | Games, tools, quizzes, e-books, catalogues | Shops, blogs, portals, dashboards |
If your project has no server and no database, HTML to APK is the better fit: it's faster, private and doesn't depend on hosting.
Prepare your HTML in five minutes
- Viewport tag. Put
<meta name="viewport" content="width=device-width, initial-scale=1">in the<head>. Without it the page renders at desktop width and looks tiny. - Relative paths. Use
css/style.css, not/css/style.cssorC:\Users\.... Paths that start with a slash or a drive letter break inside an APK. - Exact file names. Android is case-sensitive:
Logo.PNGandlogo.pngare different files. Match the case in your HTML. - Local copies of libraries. If the app must work offline, download jQuery, Bootstrap, fonts and other CDN files into the project instead of linking to them.
- Save data with localStorage. Scores, settings and notes saved with
localStoragesurvive closing the app. - Tap-friendly UI. Buttons around 48 px tall, no hover-only menus.
Not sure your project is ready? Drop it into the HTML & ZIP APK checker — it flags absolute paths, missing files, case mismatches and a missing viewport tag in your browser.
Convert HTML to APK, step by step
- Install the builder. Get HTML & ZIP to APK Builder from Google Play and sign in once.
- Choose HTML file or ZIP. One self-contained
.htmlfile can go straight in. Anything with separate files goes in as a ZIP withindex.htmlat the top level — see ZIP to APK. - Brand it. App name, a 512 × 512 icon, theme colour and a package name like
com.yourname.quizapp. - Build. The APK is compiled and signed in the cloud. The free plan bundles up to 5 MB of files; Pro raises that to 18 MB.
- Install and test. Turn on airplane mode and open the app — if it still works, it's truly offline.
Does JavaScript work?
Yes — all modern JavaScript runs, including ES modules, canvas, WebGL, Web Audio, fetch to online APIs and frameworks like React, Vue or Svelte (upload the built output folder, such as dist/ or build/, not the source). Audio may need a first tap before it plays, which is standard Android browser behaviour.

Frequently asked questions
How do I convert HTML to APK?
Open HTML & ZIP to APK Builder, pick your HTML file or a ZIP of your project, set the name and icon, and tap Build. You get a signed APK that works offline.
Can I convert HTML, CSS and JavaScript to APK?
Yes. Put them in one folder with index.html at the top, zip the folder's contents and upload the ZIP. Every file is packed inside the app.
Is there an HTML to APK converter online for free?
Yes — the build runs online in the cloud and is free for signed APKs with no watermark. You start it from the free Android app.
Will my HTML app work offline?
Yes, as long as every file it needs is inside the ZIP. Links to CDNs and online APIs still need a connection.
Can I convert an HTML5 game to APK?
Yes. Export the game for HTML5/web, zip the export folder's contents and build it. Add touch controls if the game was made for keyboard.
How big can my HTML project be?
Up to 5 MB of bundled files on the free plan and 18 MB with Pro. Compress large images to WebP to stay under the limit.
