Runs where your file already is
16kb Checker unpacks and analyzes APK and AAB packages entirely in your browser. Nothing is uploaded to our servers for the scan—ideal for private builds and NDAs.

About
Why 16kb Checker exists, how it respects your files, and who builds it.
The product
A fast, honest preview of your Android build
Upload on the home page, pick Studio or Strict mode, and get a structured report you can act on—or export for the rest of the team. No accounts, no cloud scan queue.
Built around Play's 16 KB story
We focus on what teams stress-test before release: 64-bit native alignment, zip layout hints, manifest clarity, size breakdown, and short fix guidance tied to what we actually saw in your file.
Made for humans, not just CI logs
Exports (JSON, CSV, HTML), readable tables, and a calm layout so PMs, QA, and engineers can share one report without everyone installing Android Studio.
