Page Weight Analyzer
Measure transferred page weight by HTML, CSS, JavaScript, images, fonts, and third-party resources without guessing browser-only metrics.
Uses the same low-cost public URL safety model as Website Speed Test. Uncompressed sizes appear only when reliably available.
Limitations
Use the result as planning guidance
- Low-cost HTTP-lite test, not a full browser run.
- Uncompressed resource size is shown only when reliably available.
- Resource discovery is bounded and based on public HTML references.
