Sign APK
Upload an RSA private key and its X.509 certificate (the standard Android .pk8 + .x509.pem pair), then re-sign the APK with the JAR (v1) scheme. Nothing is uploaded. The output is a v1-only package (the v2/v3 block is stripped) that installs through sideload.

Questions and answers
APK Viewer FAQ
Does the APK leave my computer?
No. The file is read locally in your browser, parsed as a ZIP and inspected on the spot. It is never uploaded to the 73hi server.
What information does the viewer show?
Package name, version name and code, minimum and target SDK, the signing scheme (v1 JAR, v2, v3, v3.1), the certificate subject and issuer, MD5 / SHA-1 / SHA-256 fingerprints, declared permissions, activities, services, receivers, providers and a full file listing.
Can it read the app icon and label?
Yes. The viewer resolves the manifest label and launcher icon, including references into the compiled resource table, and renders the icon directly from the APK.
Is there a file size limit?
The whole file is loaded into memory, so very large APKs may be slow or run out of memory on low end devices. Typical apps parse in a fraction of a second.
Can I sign an APK here?
Yes. Open the APK, then upload an RSA private key (PKCS#8, the standard Android .pk8) and its X.509 certificate. The tool re-signs the package with the JAR (v1) scheme entirely in your browser and downloads the signed file. Nothing is uploaded.
