Web to APK: convert a web app into an Android app

Quick answer: Web to APK conversion packages a web app in an Android shell so it installs and launches like a native app. You give the builder an HTTPS URL (or an HTML ZIP), plus an app name, package ID and 512×512 icon; it runs a real Gradle release build in the cloud and returns a signed APK, or an AAB for Google Play.

A web app is already an app — it just has no icon. Web to APK closes that last step: the product stays where it is, on your server, and Android gets a package that opens it full screen without an address bar.

This page is about what changes when a web app becomes an APK, and the specific things that break in the conversion, because those decide whether the file is usable or just installable.

What the conversion actually does

The builder generates an Android project whose main activity hosts your origin, compiles it with Gradle against the current SDK, signs the release output with the project keystore, and hands back the artifact. Nothing is rewritten: your React, Vue, WordPress or plain HTML site keeps running exactly as it does in a browser.

That is also the honest limit. A converted web app inherits the browser's constraints: it needs a connection, it cannot read a sensor the browser does not expose, and heavy native features stay out of reach. When those matter, a native build is the right answer and a conversion is not.

The five things that break, and the fix for each

OAuth redirects: Google sign-in refuses to render inside a WebView ("disallowed_useragent"). The build routes OAuth hosts into a Custom Tab so the session returns to the app; test the login on a real device, not a desktop browser.

File uploads: a web form that opens the camera or the file picker needs the matching Android permission and a WebView client that forwards the chooser. Test uploading a photo and a PDF before shipping.

External links: a link to another domain that opens inside the shell traps the user with no browser controls. It should open in the system browser, and the build adds that routing — verify with one link you know.

Back button: Android back must walk your in-app history and then exit, not close the app on the first tap. Hash routing is the usual culprit when it misbehaves.

Offline: a converted app with no service worker shows the browser's error page the moment the signal drops. Ship a cached shell and a real offline screen, or accept that the app is online-only and say so.

APK or AAB — pick by where the file goes

Take the APK to install on a phone, hand to a client, or distribute outside Play. Take the AAB to upload to Google Play, which splits it into per-device APKs. Both come from the same source and the same signing key.

New apps and updates submitted to Play after 31 August 2026 must target Android 16 (API level 36). The builder pins that value; if you compiled elsewhere, run the free APK checker on the file before you upload it.

What to prepare before you press build

A production HTTPS URL that works on a phone (test it in mobile Chrome first), a package ID you control (com.yourbrand.app — it is permanent), a 512×512 PNG icon, and a decision about the app name that appears under the icon.

Then build, install the APK on a real device, and walk the three flows that matter: sign in, upload a file, open an external link. If those survive, the conversion is sound.

Frequently asked questions

Is web to APK the same as a website to APK converter?

It is the same operation with different emphasis: "website" usually means a marketing site, "web app" means a logged-in product. Both inputs are an HTTPS origin (or an HTML ZIP), and both outputs are a signed APK or AAB.

Does the converted app update automatically?

Yes when it loads your live URL: deploy on the web and the app shows the new version on next open. A ZIP build is bundled, so it only changes when you rebuild and reinstall or upload a new version.

Will Google Play accept a converted web app?

Only if it adds something a browser tab does not — offline handling, native navigation, notifications, a persistent login. Play rejects thin WebView wrappers under its minimum-functionality policy; the Play rejection guide lists the twelve failures reviewers cite most.

Can I convert a web app to iOS the same way?

No. This toolchain produces Android packages only. iOS needs an Apple toolchain and a different signing process, which is why the comparison page separates prompt-to-native builders from Android packaging.
