An APK File Checker & Analyzer helps you inspect an Android APK file directly in your browser. You can check the APK file size, package name, app version, Android SDK information, permissions, file structure, and cryptographic hashes such as SHA-256 and SHA-1.

Our free APK analyzer is designed for quick, basic APK inspection without requiring you to install desktop software.

What Is an APK File?

APK stands for Android Package Kit. It is the file format used to install applications on Android devices. An APK can contain important information about an Android application, including:

• App name
• Package name
• Version information
• Android compatibility information
• Requested permissions
• Application resources
• DEX files
• Signing-related files
• Other application files

Checking this information can be useful before installing an APK from a source you do not normally use.

Free APK File Checker

Use our APK File Checker & Analyzer to inspect an APK file online.

Simply select your .apk file and click Analyze APK. The tool processes the file in your browser and displays the information it can detect.

You do not need to manually extract the APK or use complicated Android development software.

What Can This APK Analyzer Check?

1. APK File Name

The analyzer shows the original name of the APK file you selected.

2. APK File Size

You can quickly see how large the APK file is, which can be useful when comparing different APK versions.

3. Package Name

The package name uniquely identifies an Android application.

For example:

com.example.app

Package names can help you determine which application an APK is associated with.

4. App Version

The tool attempts to detect the APK’s version name and version code.

This can help you compare different versions of the same Android application.

5. Minimum Android Version

The analyzer can display the minimum Android API level supported by the application when this information is available in the APK manifest.

6. Target Android Version

You can also check the target Android API level declared by the application.

7. APK Permissions

Android applications can request different permissions.

Our APK analyzer attempts to identify permissions such as:

• Camera
• Microphone
• Location
• Contacts
• SMS
• Phone
• Internet
• Bluetooth
• Call logs

Permissions do not automatically mean that an APK is dangerous. They simply show what access the application has requested.

Check APK SHA-256 and SHA-1

The tool also calculates cryptographic hashes for the selected APK.

SHA-256

SHA-256 creates a unique fingerprint for the file.

If two APK files have the same SHA-256 hash, their contents match.

This can be useful when a developer or trusted source provides a SHA-256 checksum for an APK.

SHA-1

The tool also calculates the SHA-1 hash of the selected APK.

SHA-1 is older than SHA-256, but it can still be useful for file identification and comparison.

APK Structure Checker

An APK is essentially a packaged collection of files.

The analyzer checks for common APK components such as:

• AndroidManifest.xml
• classes.dex
• resources.arsc
• lib/
• assets/
• res/
• META-INF/

This gives you a quick overview of the APK’s internal structure.

Does the APK Get Uploaded?

The analyzer is designed to process the selected APK directly in your web browser.

The tool does not intentionally upload the APK to a website server for analysis.

However, you should always avoid uploading or processing files that contain sensitive personal information on websites you do not trust.

Is an APK Checker the Same as a Malware Scanner?

No.

This is very important.

An APK analyzer can inspect file information, permissions, hashes, manifest information, and other static indicators. However, these checks cannot guarantee that an APK is completely safe or malware-free.

A suspicious permission does not automatically mean that an application contains malware.

Likewise, a valid SHA-256 hash only confirms that the file matches another file with the same hash. It does not prove that the application is safe.

For stronger security analysis, use a reputable mobile security solution and obtain APK files from trustworthy sources.

Why Check an APK Before Installing It?

Checking an APK can help you understand what you are about to install.

For example, you may want to check:

• Which package the APK belongs to
• Which version you downloaded
• How large the file is
• Which permissions it requests
• Which Android versions it targets
• Whether its checksum matches a trusted checksum
• What common files exist inside the APK

This is especially useful when comparing APK files from different sources.

How to Use the APK File Checker

Using the tool is simple:

Step 1: Open the APK File Checker & Analyzer.

Step 2: Click Choose APK File.

Step 3: Select an .apk file from your device.

Step 4: Click Analyze APK.

Step 5: Review the APK information displayed by the tool.

You can also copy the SHA-256 or SHA-1 checksum for comparison.

Frequently Asked Questions

What is an APK checker?

An APK checker is a tool that examines an Android APK file and displays useful information such as package name, version, permissions, file size, hashes, and other metadata.

Can I check an APK online?

Yes. Our browser-based APK File Checker & Analyzer allows you to inspect supported APK information directly from your browser.

Can I check APK permissions?

Yes. The analyzer attempts to read the Android manifest and display requested permissions when they can be successfully decoded.

Can I check an APK package name?

Yes. The tool attempts to extract the package name from the APK’s Android manifest.

Can I calculate an APK SHA-256 hash?

Yes. The tool calculates the SHA-256 checksum of the selected APK directly in your browser.

Does a SHA-256 match mean an APK is safe?

No. A matching SHA-256 means the files have matching contents. It does not prove that the application is malware-free.

Is this APK analyzer a virus scanner?

No. It is a static APK information and analysis tool, not a complete malware scanner.

Can I use this tool on mobile?

Yes. The interface is designed to work on modern mobile and desktop browsers. Your browser and device must allow you to select the APK file.

Final Thoughts

An APK can contain a lot of useful technical information that is not immediately visible from its filename.

The APK File Checker & Analyzer provides a simple way to inspect an APK’s basic information, permissions, structure, and file hashes without installing additional software.

If you regularly download or compare Android APK files, checking the file before installation can give you a better understanding of what you are dealing with.

Always remember: APK analysis can provide useful information, but no basic online checker can guarantee that an APK is completely safe.
