Completely. Our converter processes your KML file 100% in your browser using client-side code. It never leaves your device or touches any external server.
It depends on the formats. Converting from lossless to lossy (e.g. PNG to JPEG) may reduce quality. Converting lossless-to-lossless (e.g. PNG to WebP lossless) preserves all quality.
