Free online APK to ZIP converter

An APK may need a .zip extension when an archive tool, upload system, or recipient accepts ZIP files but does not recognize APK files. Because an APK already uses the ZIP container format, this usually requires only an extension change, not recompression.

APK format

An APK (Android Package Kit) is the package format used to distribute and install Android applications. Android developers create APKs with Android Studio and Gradle; users may receive them from app distributors, device-management systems, or direct downloads.

An APK normally contains compiled Dalvik/ART code in classes.dex, the manifest, resources, assets, native libraries, and signing data. Its file records use ZIP structures, so archive programs can usually browse and extract an APK without converting its contents.

ZIP format

ZIP is a general-purpose archive format that combines files and folders into one file and can compress supported data. Windows File Explorer, macOS Finder, 7-Zip, WinRAR, and command-line tools such as unzip support ZIP archives.

Using a ZIP extension can make an APK easier to inspect or share with systems that filter unknown extensions. Changing .apk to .zip does not reduce the file size, because APK entries are already stored or compressed as determined by the Android build process.

Convert by changing the extension

Rename the file rather than extracting and creating a new archive. Renaming preserves every byte, including Android signing blocks and ZIP metadata.

• On Windows, enable View → Show → File name extensions in File Explorer. Rename app.apk to app.zip and accept the warning.
• On macOS, select the file in Finder, press Return, replace .apk with .zip, and confirm the extension change.
• On Linux or macOS Terminal, run mv app.apk app.zip.
• On Windows Command Prompt, run ren app.apk app.zip.

To retain the original APK, make a byte-for-byte copy with the new extension: use copy app.apk app.zip in Windows Command Prompt or cp app.apk app.zip on macOS and Linux. The built-in converter on 101convert.com can also create a ZIP-named copy without installing software.

Open the resulting file with 7-Zip, WinRAR, Finder, or an extraction command such as unzip app.zip -d app_contents. An archive utility may also open the original .apk directly, making a rename unnecessary when inspection is the only goal.

Compatibility and editing limits

A renamed file contains the same Android package, but software that selects installable packages by filename may require the .apk extension. Rename it back to .apk before using it with an Android installer.

Do not extract, modify, and recompress an APK if the original must remain installable. Changing files or rebuilding the ZIP invalidates its signature. A modified package must be rebuilt correctly and signed again, typically with Android build tools and apksigner; it also cannot replace an installed app unless it is signed with the same signing key.

Files such as .xapk, .apks, and .apkm are often ZIP-based bundles containing split APKs and installer metadata. Renaming one to .zip can expose its contents, but it does not turn the bundle into one installable APK.
