Hi Product Hunt! šŸ‘‹ I'm the maker of MakeBW. I built this tool because I often needed to quickly check how a UI design looks in grayscale, or prepare images for my e-ink reader, but I hated uploading my private photos to random servers just to apply a simple filter. MakeBW runs entirely in your browser. No data is sent to the cloud, making it safe for personal or sensitive images. It's also great for turning photos into line art/coloring pages for kids! Key features: 100% Client-side processing (Privacy focused) Supports Grayscale & Dithering algorithms Free to use I'd love to hear your feedback or suggestions for new filters! Thanks for checking it out! šŸš€
