Output settings
Quality applies to JPEG/WebP. PNG/BMP ignore quality.
Your images never leave your browser. Conversion runs locally on your device.
Lossless vs lossy
PNG/BMP are lossless (no quality slider). JPEG/WebP use quality to trade size vs clarity. Pick the format that fits your needs.
Transparent images
Converting to JPEG fills transparent areas with white. PNG/WebP/BMP preserve transparency in browsers that support it.
Browser-only
Everything happens on-device. If your browser cannot encode a format, we alert you and fall back to PNG to keep conversion private and reliable.
