Threshold image
Runs locally in your browser. The selected image is not uploaded by this tool.
JPEG, PNG, and WebP are supported by default. Specialized converters restrict the file picker to their required input format.
How to use
Upload an image
Choose a JPEG, PNG, or WebP image from your device.
Set the threshold
Choose a preset or move the threshold slider. Lower values make more pixels white; higher values make more pixels black.
Preview
Generate the preview to inspect the black and white result, then invert it if you need a mask or negative.
Download
Save the processed image as a PNG.
Features
Adjustable threshold
Set the cutoff from 0 to 255 or start with presets for sketches, scans, and stencil-style output.
Pure black and white
Every output pixel is mapped to RGB 0 or RGB 255, with an invert option for masks, negatives, and cut paths.
Client-side processing
Canvas processing runs locally in your browser, so the uploaded image stays on your device.
PNG download
Export the thresholded result as a flattened PNG ready to save or share.

Common questions
Does this create grayscale?
+
No. The output uses only pure black and pure white pixels. Use the invert option when the black and white areas need to swap.
Are transparent images supported?
+
Yes. Transparent pixels are flattened onto white before thresholding.
