Luma autocorrelation estimates repeating periods and reports the analyzed sample and estimator score.
Free local manga preflight
Check manga screentone images before resize or print
Inspect a local manga tone raster at true 100% pixel scale, estimate its horizontal and vertical repeat periods, and compare it with a clearly labeled resize simulation.

Separate simulation
A new local resample is labeled as simulated instead of being presented as a detected defect.

Source and output panels expose a scrollable 100% mapping for practical visual review.
Manga Screentone Checker FAQ
Production answers without the guesswork
Does the checker detect moire automatically?+
It estimates repeating raster periods. The risk score is a separate sampling simulation and is not presented as detected moire.
What happens to my uploaded image?+
The file is decoded and analyzed in the browser tab. It is not sent to LlamaGen or another server.
Why can the 100% view differ between devices?+
One file pixel maps to one CSS pixel, but browser zoom, operating-system scaling, and device pixel ratio can still affect the physical display.
