What this tool is for
Convert to grayscale using luminance weighting, which preserves the perceived brightness of colours instead of flattening a bright red and a dark blue into the same grey. Intensity is adjustable, and sepia is a click away. Your images are processed by your own browser through the Canvas API. They are never uploaded, which means no queue, no size limit imposed by a server, and no copy of your photo sitting in someone else storage.
