MSI to APK Converter
Processing entirely on your device — large files may take a moment.
Windows Installer Package and Android Package exist for different jobs: MSI is the Windows Installer database: a COM-structured file holding the program files, registry entries and install logic of an application. Everything an installer would unpack lives inside it. Repack an APK as ZIP to inspect its manifest and assets (not for reinstalling).
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How MSI compares to APK

About the MSI format
MSI is the Windows Installer database: a COM-structured binary that holds every file, shortcut, registry entry and install sequence an application needs. Running the installer is one way in — extraction is the other, and it needs no Windows at all.
Extracting an MSI lays out its contents as files: binaries, DLLs, resources, even the install logic tables. Security teams audit them this way, IT departments pre-stage deployments this way, and curious users finally learn what "installing" actually does.
+ Strengths
- ✓Inspect installers without running them
- ✓Works cross-platform — no Windows needed
- ✓Files come out exactly as the installer would lay them
! Limitations
- −Registry and shortcut logic are not files
- −Large installers extract to large trees
- −Nested CAB payloads may need a second pass
About the APK format
An APK is Android’s install package: a ZIP holding AndroidManifest.xml, compiled DEX bytecode, native libraries and assets. Unpacking one is the standard first step of security review, compatibility checks and asset recovery.
One honest limit: unpacking is inspection, not installation — a repacked ZIP cannot be installed back onto a phone, and the page says so.
+ Strengths
- ✓Everything an Android app ships
- ✓ZIP-based, easy to unpack
- ✓Manifest readable as XML
! Limitations
- −DEX bytecode is not human source
- −Repack cannot reinstall
Why convert MSI to APK?
Converting makes sense where the strengths of APK meet what MSI cannot give you. Everything an Android app ships Meanwhile Registry and shortcut logic are not files One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MSI to APK converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MSI to APK?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the MSI file.
Are the files inside my MSI archive modified?
No. Contents are unpacked in memory and repacked into APK byte-for-byte — the conversion changes the container, never the files inside it.
