About this tool
This compressor reduces image file size by re-encoding with adjustable quality, entirely in your browser — your photos never leave your device. Use the quality slider for general compression, or set a target size in KB when a portal demands a maximum (e.g. under 100 KB). The tool automatically finds the best quality that fits your target.
