Image Tools
Compress Image
Shrink image file size without uploading to a server. PrivyTool runs compression locally in your browser for speed and privacy.
Compression
Preview and file size update live. Export format is shared across all tools.
Lower quality = smaller file. Higher quality = better detail.
PNG keeps sharp edges; JPG/JPEG are smaller photos; WebP/AVIF are modern and usually smallest.
