为什么只导出 WebP？Why does it only export WebP?
本页是 WebP 系列工具之一：读入图片后把与所选颜色相近（按容差）的像素设为透明，再按 WebP 格式导出，便于在 WebP 工作流里直接使用。需要 PNG 或 JPG 结果时，请用对应的通用图片工具。This page is one of the WebP tools: it loads the image, makes pixels close to the chosen colour (within the tolerance) transparent, and exports the result as WebP so it fits straight into a WebP workflow. For PNG or JPG output, use the matching general image tool.
会上传吗？Uploaded?
不会，图片只在浏览器本地处理。No. Processed locally in your browser.
容差怎么算？How does tolerance work?
按 RGB 欧氏距离：距离 ≤ 容差 × 255 ÷ 100 的像素被清除。容差 0 只清除与所选颜色完全相同的像素；容差 100 的半径正好是 255，边界上的颜色也包括在内。像素直接从解码后的原图读取，不经过有损中间步骤；无损 WebP 输入会按无损导出。By RGB (Euclidean) distance: pixels within tolerance × 255 ÷ 100 of the chosen colour are cleared. Tolerance 0 clears only pixels exactly equal to the colour; tolerance 100 has a radius of exactly 255, boundary included. Pixels are read straight from the decoded image with no lossy intermediate step, and a lossless WebP input is exported lossless.
有哪些选项可以调整？What options can I adjust?
