XXE to APK Converter
Processing entirely on your device — large files may take a moment.
xxencoded File and Android Package exist for different jobs: XXE is xxencode's answer to uuencode — the same 4-for-3 packing but with an alphabet that survives IBM mainframe EBCDIC gateways. Repack an APK as ZIP to inspect its manifest and assets (not for reinstalling).
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the XXE format
XXE is xxencode's output: the same 4-for-3 packing as uuencode, but with an alphabet (+- and alphanumerics) chosen to survive EBCDIC systems — the IBM mainframe text encoding that mangled uuencoded files crossing gateways.
The decoder is identical arithmetic with a different lookup table; payloads decode back to the original binary (often a tar) ready for repackaging.
+ Strengths
- ✓EBCDIC-safe alphabet
- ✓Same simple packing as UUE
- ✓Decodes with a table swap
! Limitations
- −Extremely rare today
- −EBCDIC gateways themselves are gone
- −Dialects differ between implementations
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

Frequently asked questions
Is this XXE 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 XXE 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.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
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 XXE file.
