What does the tamper heatmap detect?

It highlights JPEG compression differences. Strong hotspots can indicate manipulation or multiple save cycles, but they are not final proof on their own.

Can this tool prove that an image is fake?

No. Use heatmaps as forensic hints and combine them with metadata checks, source verification, and contextual investigation.

Do you upload my image?

The core heatmap generation runs in-browser. This tool is designed for privacy-first forensic workflows.

What should I do after finding suspicious hotspots?

Cross-check with EXIF Viewer, Reverse Image Search, and AI Location Search if needed to validate timeline and origin.

Compression anomaly view

Heatmaps visualize unusual JPEG compression patterns that can indicate edited or recompressed areas.

Interactive controls

Fine-tune amplify and contrast to inspect subtle regions without leaving the browser.

Client-side processing

Your analysis runs locally in the browser, helping keep sensitive images private.

Best practice for reliable results

Always compare hotspots against natural high-detail areas such as foliage or text.
Test multiple slider settings before deciding whether a region is truly suspicious.
Use heatmaps as indicators only, then validate with metadata and source checks.
