Why a KB target instead of a quality slider?
Most compressors ask you to guess a quality percentage and hope the result fits. Government forms, university applications, and job portals reject files over a strict limit — 20 KB here, 240 KB there. KB Target works backwards from your limit: it binary-searches the encoder quality until the output lands just under your number, so you never resubmit a form twice.
Private by design
Everything runs in your browser with WebAssembly encoders from Google's Squoosh project. Your photos, signatures, and documents are never uploaded — there is no server that could see them. That matters most for passports, ID cards, and signed documents.
