How to use Create Black and White WebP
- 1. Load the WebP to threshold. Drop or browse for the WebP image you want reduced to two tones. The tool reads its brightness values across every pixel before applying the cutoff.
- 2. Set the Threshold. Drag Threshold (0 to 255) to decide the brightness cutoff. Pixels above it snap to pure white, pixels below it snap to pure black. A middle value near 128 suits most photos.
- 3. Download the stencil-style WebP. Download the result once the balance of black and white areas looks right, a high-contrast two-tone version of the original image.
When to use Create Black and White WebP
Create Black and White WebP forces every pixel to pure black or pure white around a brightness threshold you set, producing a stark, stencil-like image rather than a soft grayscale. It suits graphic, high-contrast treatments.
- Making a stencil for laser cutting or engraving. A hobbyist preparing artwork for a laser cutter needs a strict two-tone image, and adjusting the threshold produces a clean black-and-white version ready for the cutting software.
- Creating a bold poster-style graphic. A poster design calls for a high-contrast portrait rather than a photographic one, and thresholding a photo at the right cutoff produces that stark graphic look.
- Simplifying a photo for a low-color display. An e-paper or 1-bit display can only show pure black and white pixels, and thresholding a source photo first prepares it correctly for that hardware's limitations.
Examples

You can shape the output with the Threshold (0–255) setting, and the result refreshes the moment you change it.
