Each pixel's perceptual brightness is compared to your threshold (0–255, default 128); anything brighter becomes white, anything darker becomes black. Great for high-contrast art, line work, sketches, and screen-print prep. Output format matches the input where possible, defaulting to PNG. Everything runs locally in your browser.","category":"image","categoryName":"Image","keywords":["black and white image converter","image to black and white","convert image to bw","image threshold filter","bw image online","two tone image","black white image online","monochrome image converter","image to monochrome","image to black white online free","high contrast image converter","threshold image online"],"url":"https://freepngtojpg.com/image-to-bw","runsOn":"client","multiple":false,"batch":false,"input":{"type":"file","extensions":[".png",".jpg",".jpeg",".webp",".gif",".bmp",".avif"],"mimeTypes":["image/png","image/jpeg","image/webp","image/gif","image/bmp","image/avif"]},"output":{"type":"file","extension":".png","mimeType":"image/png"},"options":[{"type":"number","key":"threshold","label":"Threshold","defaultValue":128,"min":0,"max":255,"step":1,"help":"Pixels brighter than this become white; darker pixels become black."}],"invocation":{"webUi":"https://freepngtojpg.com/image-to-bw","api":null,"notes":"Currently runs client-side in the user's browser.
