Threshold converts every pixel to either pure black or pure white based on a brightness cutoff you control, commonly used to clean up scanned documents or create high-contrast line art.

よくある質問 (FAQ)

Does this permanently change my original file?

No. The effect is applied to a copy rendered in your browser. Your original image on disk is never touched — you download a new file with the effect applied.

Can I adjust the intensity before downloading?

Yes. Every slider updates the preview in real time, so you can fine-tune the effect before exporting the final image.

What format is the downloaded file?

PNG, to preserve full quality and, where relevant, transparency.
