Lumetry

Lumetry decodes, edits, and exports RAW camera files entirely in your browser using WebAssembly, so nothing gets uploaded. You can also describe an edit in plain English, like warm golden hour with the shadows lifted, and it turns that into real slider values instead of a filter. Free for the first 100 photos, a free account raises that to 250 a month, and Pro removes the cap at $7/month.
