Compare the file, byte for byte.

1. Finish the intended APK download and locate the file on your device.
2. Select that file in the tool. The browser reads its bytes locally using Web Crypto.
3. Wait for a result showing its byte count and SHA-256.
4. Check whether both match the dated record. If either differs, leave installation paused while you establish why.

The tool supports files up to 200 MB to avoid excessive memory use. It requires a browser with Web Crypto in a secure context. A protected, unavailable or partially downloaded file may fail to read; no alternate upload is attempted.

A SHA-256 match is strong evidence that the selected bytes are the same as the measured file. The exact byte count is an additional useful check. A same-size file can still contain different bytes, so size alone is insufficient.

A hash is not a malware scan, a signing-certificate verification, proof of publisher ownership or confirmation that the app works on your device. A matching package name can also appear in a differently signed file. Use the installation decision only after you have considered the actual source and device prompts.

Check that you selected the correct file, not another downloaded version, an incomplete file or an HTML error page. Do not rename a file merely to make it look like an APK. The source can also replace a file behind the same address after this observation.

A mismatch is a reason for a fresh source review, not proof by itself of malicious intent. Keep installation paused. The update guide explains why a different version must be compared as its own record.
